Multiple Marriages in the 1910 Census

The United States federal census provides a framework for tracing families every ten years (except the mostly destroyed 1890). Later census forms asked more detailed questions of all members of households.

Marital status became a question in 1880.

The 1910 census asked two questions about marital status:

Question 8. Whether single, married, widowed, or divorced.

Question 9. Number of years of present marriage.

Questions on the 1910 federal census.
Questions 8 and 9 pertained to marital status.

Enumerators were to mark answers in accordance with rules that are not reflected on the census form. The rule for question 8: ". . . if this is the first marriage, write 'M1,' but if this is the second or subsequent marriage, write 'M2' (meaning married more than once)."

Instructions to the enumerator about how to record the answer
to Question 8 about marital status

Answers on the census can be wildly inaccurate. But the 1910 census can mislead the researcher with the answers about marriage. M1 means first marriage, but M2 means more than one marriage, not necessarily the second marriage.

We will look at two people to illustrate this question in the 1910 census, Albert Baldwin Duryea (1853-1924) and Minnie Tuthill (1870-1941).

Albert Baldwin Duryea

Albert was the son of George Winfield Duryea (1823-1892) and Barbara Ann Savidge (1825-18xx). He was born around 1853, probably in Montgomery, Somerset County, New Jersey.

On March 18, 1882 Albert married Margaret Lear Heavener (1851-1903) in Upper Black Eddy, Bucks County, Pennsylvania. This union produced two children, Paul Gamble Duryea (1883-1966) and Edwin Jayne Duryea (1886-1942).

On May 6, 1905 Albert married Virginia Stryker (1854-1907) in Trenton, Mercer County, New Jersey. Virginia was the widow of William S Barr. She died two and a half years later from cancer of the bowels.

On May 15, 1908 Albert married Elizabeth Tinsman Morris (1850-1925) in Trenton.

This brings us to the 1910 census. Albert Duryea and his wife Elizabeth were enumerated in Trenton with a boarder, William Hillpot.

Household of Albert Duryea

For Question 8, "M2" is written for the marital status of Albert and Elizabeth. Elizabeth had at least one prior marriage (looks like "Comly") on her marriage certificate to Albert. We found three marriages for Albert. This is an illustration of M2 properly indicating more than one marriage and not second marriage.

Close up of 1910 federal census
Albert was on marriage number 3. "M2" was the correct response.

Minnie Tuthill

Tuthill or Tuttle and variations is a popular name from Suffolk County, New York. Minnie was born around 1870 in Riverhead to Albert Daniel Tuthill (1846-1920) and Hannah Erskine (1847-1927).

Minnie's marital history is vague at times, but we will see what we can see.

On January 10, 1887 Minnie C Tuthill married John Edwin Duryea in Riverhead- according to the New York State Marriage Index. As of this writing, New York is still refusing to release genealogical copies of records.

In the 1900 census, Minnie Gusswiller was enumerated in Jersey City, Hudson County, New Jersey with her husband, Frank Gusswiller. They were married for nine years. She had six children, four still living, listed with birth years from 1888 through 1899, all using the surname Gusswiller.

John E Duryea died February 22, 1901 in Trenton, Mercer County, New Jersey. 

Death certificate of John E Duryea

If Minnie Tuthill married Frank Gusswiller around 1891, she would have need to have divorced her first husband, John Duryea. I use "if" because I have not found a possible entry in the marriage indexes for Minnie and Frank in New Jersey, New York, and New York City.

This brings us to the 1910 census. Minnie Woodin and her husband, William Woodin, were enumerated in Poughkeepsie, Dutchess County, New York. His marital status was "M1," married five years. Her marital status was "M2," married five years. She had ten children, six still living. With them were five children. Four children were named Gusswiller and were ages 9 through 19. William Woodin, final child, was three years old.

Household of William Woodin

Close up of 1910 federal census
Minnie was on marriage number 2 or 3. "M2" was the correct response.

The answer "M2" means that she was married at least twice and is not indicative of whether she and Frank Gusswiller actually married.

Minnie continued marrying after the 1910 census. In the 1920 census, Minnie Woodin, married, was still in Poughkeepsie, but without a husband. From the New York State marriage indexes we find that on October 20, 1920 Minnie M Trythill aka Gussweller married John Henry in Beacon, Dutchess County; on July 27, 1937 Minnie Henry married Charles Hults.

Minnie M Hults died December 25, 1941 in Poughkeepsie.

Minnie's husbands as far as I can tell:

1887  John Edwin Duryea (1867-1901)

18xx  Frank X Gusswiller (1862-19xx)

19xx  William J Woodin (1868-19xx)

1920  John Henry (18xx-19xx)

1937  Charles Hults (1865-1954)

Minnie's children as far as I can find:

Edith Mabel May Duryea (1888-1943)

Everett Tuthill Duryea (1890-1937)

Elnora Frances Gusswiller (1893-1893)

Theresa Tessie Gusswiller (1895-1975)

Frances Gusswiller (1897-1898)

Ivon Albert Gusswiller (1898-1969)

Elsie Gusswiller (1901-1991)

William James Woodin (1906-1983)

Leon Ellsworth Woodin (1910-1987)

A note about Edith, the daughter of John E Duryea and Minnie Tuthill: she had a troubled life. She was born May 16, 1888 in Jersey City.

Newspaper article from the Evening Journal of Jersey City November 21, 1907.
"Mrs Gussmiller angry at her arrest."

In the 1910 census, Edith "Gusswiller" was an "inmate" at Laurel Hill in Secaucus, Hudson County. This institution housed those who were mentally ill or infirm. It was also called Snake Hill, or Hudson County Insane Asylum, and still exists today as "Meadowview Psychiatric Hospital." Edith was still there in the 1920, 1930, and 1940 censuses, but under the name Duryea, not Gusswiller.

This is why I think that the baby named "Peter Duryea or Gussweller" was hers. I did not find a birth certificate for him, but he was issued a death certificate. He died at the Hudson County Insane Hospital on January 21, 1913 from inanition. His date of birth was December 13, 1912. He was "out of wedlock." Only his mother was listed on his death certificate- "Edith Duryea or Gussweller."

I searched unsuccessfully for a marriage between Duryea and Gussweller. With the additional information gathered about Minnie Tuthill and her daughter, Edith Duryea, I think that Peter was the baby of Edith.

Burials at Laurel Hill were unmarked, which was not an unusual practice at such institutions. Laurel Hill burials included not only people from the insane asylum, but also from the alms house, tuberculosis hospital, and jail. Records were kept, but supposedly Hudson County cannot find them today. In 2002, the New Jersey Turnpike Authority sought to extend part of the Turnpike (Interstate 95) into the burial area and found bones and artifacts when construction crews started digging. It is thought that over 10,000 people were buried in this area.

When Edith Duryea died in 1943, she too was buried in an unmarked grave at Laurel Hill. Her usual address was in Poughkeepsie, connecting her to her late mother's residence since at least 1910.

When reviewing the 1910 census, be mindful that the answer "M2" for a married person means that this is at least the second marriage. You would still need to use other records to discover marriages and their disposition.

Name Change: Bostedo to Bishop

My fourth great grandfather, Reuben Levy Bishop (1805-1856) remains a tail end in my tree. I explored possible connections to other Bishops of Morris County, New Jersey, such as William Bishop (1768-1844), with origins in Connecticut.

In a work by J Percy Crayon about Morris County families,¹ I found mention of a Bishop originally being Bostedo. A change in name could cause a tail in a tree until the older versions are uncovered.

Crayon's book about families in Morris County, New Jersey.
" . . . Bostedo, or Bishop as the name was changed . . . "

I found some documentation on this name change. Please note that changing one's name was not a formal process in this time period. We are not looking for a court proceeding or newspaper announcement of the name change.

Gideon Bostedo and Mary Beach married in Pequannock, Morris County on August 2, 1803.

Research note: Marriages were recorded at the state level in New Jersey beginning in the year 1848. Prior to this, individual counties recorded the marriages. Indexes are found throughout Ancestry but the images are on Family Search.

Gideon and Mary had a son, Abner Bostedo, around 1817. Abner married Lavinia Landers (1816-1895) and they had children. Abner was a Civil War veteran who served in Company L, 27th Infantry. He died in 1890. His military service is reflected on his stone in the Bostedo Family Cemetery in Marcella, Rockaway Township, Morris County. (He is the only person listed in this vanished burial ground on Find A Grave.)

Abner's parents on his death certificate were Gideon V Bostedo and Mary Bostedo. Burial was at Greenville. This was the name of an area, more noted on a mine, near Marcella.

Then we have the person mentioned in Crayon's book, Charles Bishop (1804-1881). He married Mary Kimble (1811-1888) and they had many children. Mary's mother was Elizabeth Vanderhoof (1789-1861). (How she connects to my Vanderhoof line is unknown at this juncture.)

Charles' death certificate lists his parents as George Bishop and Mary Beach.

Why did Charles change his surname from Bostedo to Bishop? The informant of this death certificate knew Charles' father as George, not Gideon? Why did Charles change his surname but Abner did not?

Is my fourth great grandfather, Reuben Levy Bishop, from this Bostedo family? I do not know at this time. A name change could explain why Reuben appears from seemingly nowhere.

More research is needed.

Deborah Vanderhoof Decker 1805-1832

Research Question

Was Deborah Vanderhoof (1805-1832) a daughter of Jacob Vanderhoof (1772-1847) and Ann Hopler (1772-1841)?

Online family trees

Some trees posit Deborah as a child of Jacob Vanderhoof and Ann Hopler.

Marriage of Deborah Vanderhoof and John Decker, 1822

On March 19, 1822 Deborah Vanderhoof and John Decker were married by Pastor John Ford in Morris County, New Jersey. Marriages in Morris County can be found in books digitized at Family Search. The range of years is from the late 1700s through the late 1800s, including past 1848, when New Jersey required centralized recording of marriages.

"March 19 1822 John Decker, Stony Brook to
Deborah Vanderhoof of Rockaway Valley"

"March 19 1822 John Decker, Stony Brook to
Deborah Vanderhoof of Rockaway Valley"

The problem with these marriage records is that additional information is scarce. For example, ages of the parties and names of parents are often not given.

Burial and gravestone evidence

Deborah Vanderhoof and John Decker were buried at Rockaway Valley United Methodist Church Cemetery in Boonton, Morris County.

Gravestones in Rockaway Valley United Methodist Church Cemetery

Deborah Vanderhoof died March 13, 1832 
John Decker died September 5, 1877
Rachel Jacobus died November 17, 1866

The date of death etched on Deborah's stone is March 13, 1832. I'm no expert on gravestones, but I do not think that her stone was created at the time of her death; therefore, it is prone to inaccuracies. Next to Deborah is her husband, John Decker (1800-1877). Next to John is his second wife, Rachel Jacobus (1796-1866).

Children of Deborah Vanderhoof and John Decker and problems with the timeline

Deborah and John had children. Names of the children can reveal names of grandparents. John Decker's parents were Andrew Decker and Elizabeth Dulhagle. The two oldest children were named Elizabeth and Andrew. It is possible that other children were born and named after Deborah's side of the family and that we do not know about these children because they died young or they married and moved away before the 1850 census.

--Elizabeth Decker (1822-1897) married Cyrus Dixon (1814-1868)

--Andrew Decker (1827-1906) married Martha Dixon (1830-1919)

--Sarah Louise Decker (1830-19xx) married William Kanouse (1823-1903)

--Catherine Amanda Decker (1835-1915) married Charles Augustus Kincaid (1832-1901).

The year of birth for the youngest child, Catherine, varies in records, but is usually in the early 1830s. The year of birth on her gravestone is 1835. So Catherine's mother, Deborah, died anytime after her birth until her father remarried before the 1850 census. There were no recordings of deaths to the county or State of New Jersey in the 1830s. Either Deborah did not die in 1832 or Catherine was not born in 1835, or Deborah was not her mother.

Conclusion

With the information so far gathered, the parentage of Deborah Vanderhoof remains a mystery. No direct evidence links Deborah to Jacob Vanderhoof and Ann Hopler. None of the known and speculated children of Jacob and Ann named a daughter Deborah. Online trees copy one another. Further evidence is required to link Deborah to any set of parents.

If you have probate, church, or family Bible records related to Morris County Vanderhoofs, I would welcome hearing from you.

Similar Name, Different People

As I sort through the Vanderhoofs, I processed the death certificate of William H Van Derhoef. He died at age 79 years on October 9, 1943 in West Orange, Essex County, New Jersey. According to this document, his wife was Jennie Byington and his parents were John Van Derhoef and Sarah Graft. Burial was in Greenwood Cemetery in Brooklyn, New York.

William was born in the early 1860s, probably in Brooklyn. He was one of the middle children. His father, John, worked in the seafood markets and had deep roots in Monmouth County, New Jersey.

William was already entered at Find A Grave. I found his parents entered at Cypress Hills Cemetery in Brooklyn: John V Vanderhoef (1824-1900) and Sarah Ann Graff (1829-1919). Sarah's entry at Find A Grave currently has no year of death. Burials are searchable on the website of Cypress Hills. She was interred on December 11, 1919. She probably died in New Jersey, which has no index for deaths in 1919.

There is a problem with the Find A Grave listing for this family. John V Vanderhoef and Sarah Ann Graff were already attached to a son named William H Vanderhoef (1861-1930), buried in Green-Wood Cemetery in Brooklyn. 

Memorial page at Find A Grave for William H Vanderhoef
1861-1930 in Green-Wood Cemetery, Brooklyn

There are so many people named Vanderhoof or variant spellings that it is easy to mix them up. In my family tree are currently 49 people named William Vanderhoof/hoff/hoef.

The creator of William's memorial page in Green-Wood Cemetery supplied a spouse- Henrietta Dixon (1863-1908).

Marriages and deaths in New York City are digitized for these earlier years. 

On the marriage record from 1882, William J Vanderhoof's father was John Vanderhoof, but his mother was Catherine Mulligan- not Sarah Ann Graff.

Note that the death certificate lists the place of burial as Evergreens Cemetery. This is another large cemetery in Brooklyn. Although they do not have an online index, they will confirm burials via email. Because I had precise dates of death for William J, his wife Henrietta, and their son, William, Evergreens Cemetery was able to quickly confirm that the family was buried there.

The entry on Find A Grave, in contrast, lists the place of burial as Green-Wood Cemetery.

I did request changes to the memorial page of William H Vanderhoef (1861-1930) of Green-Wood Cemetery, but they were declined.

The Final Resting Place of Walter Joseph Preston

Where was Walter Joseph Preston buried?

Walter was a great granduncle on my mother's side. On August 4, 1899 he was born in Independence, Warren County, New Jersey to John D Preston (1857-1928) and Bridget A Sheehy (1857-1916). The family soon relocated to Bayonne in Hudson County. 

In 1926 Walter married Edna Armstrong (1899-1976). They had two daughters, Margaret Mary (1928-1998) and Joan Marie (1931-1912).

In the 1940s Walter and his family relocated to Elizabeth in Union County.

Walter worked on the East Jersey Railroad. He was at work when he died of a heart attack on April 23, 1957.

Walter's father, John, died on the railroad in Bayonne in 1928, but because he was struck by a train while working. Walter's brother, Michael, also died on the railroad in 1918, perhaps from jumping out of the train after missing his stop.

The place of burial differs on both documents concerning Walter's death. The death certificate has St Gertrude Cemetery in Woodbridge. The obituary has Holy Name Cemetery in Jersey City.

Neither document is a primary source for the burial.

I have the records for Preston at Holy Name Cemetery. Walter is not listed with them. The records (not in their entirety) were microfilmed and can be viewed at a Family History Center or Affiliate, but not from home. FamilySearch offers a searchable index of the index that you can view at home.

Find a Grave provides a memorial page for Walter in Saint Gertrude Cemetery in Colonia, Middlesex County. Someone has taken a picture of the stone that Walter and Edna share.

Family Tree Repair: Hiley VanDerHoof 1803-1888

I was excited to find this family tree with additional details about my fourth great grandmother, Elizabeth Vanderhoof (1799-1878). Then I realized the creator combined Elizabeth with Hiley Vanderhoof (1803-1888). These were two different women living in Morris County, New Jersey in the 1800s.

One of the red flags on this tree is that the person died in 1878,
but was enumerated in the 1880 federal census.

Hiley was spelled differently in various records. "Hiler" is a surname in the area. I do not know if this is the source of Hiley's first name.

• Hyla on her 1823 marriage record to William Cook
• Hiley in census entries
• Hylia on her death certificate
• Hila on her gravestone

Hiley and Elizabeth were two different people. They were probably sisters. They married two Cook brothers.

Hiley's first appearance in the census is in 1850 in Rockaway, Morris County. Her husband, William Cook, is not listed with her and is presumably deceased. In her household is Jacob Cook, age 26, married within the year. Sarah Cook, age 20, married within the year. William Cook, age 11. Sarah was probably Jacob's wife and not a daughter of Hiley and William. She is not with Jacob in the 1860 census and presumably died between 1850 and 1860.

Elizabeth died in 1878. She was buried with her husband, Stephen Cook, in the small Cook Cemetery in Denville. The few remaining stones are nestled on the grounds of the Rockaway River Country Club Golf Course.

Elizabeth Vanderhoof and Hiley Vanderhoof were two distinct people, contrary to the online trees floating around.

Mary (1822-1861), Not a Daughter of Jacob Vanderhoof and Ann Hopler

Beware of blindly accepting published family trees!

Jacob Vanderhoof (1772-1847) and Ann Hopler (1772-1841) lived and died in Morris County, New Jersey. This couple produced thousands of descendants, myself included. As a consequence, they are found in lots of online family trees. Vanderhoof and variant spellings were common in New York and New Jersey in the 1700s and 1800s, resulting in many different people having similar first and last names living within miles of one another. The few written records that survive lack details that would help distinguish one person from another of the same name.

The result is lots of trees that merge different people into one, or criss-cross the lines.

As of this writing, I have not sorted all of the men named Jacob Vanderhoof. I'll produce articles as I figure out children, record sets, or locations.

A tree appeared with Jacob, Ann, and sixteen children. I explored this tree because I was curious about the sources about their daughter, Elizabeth (1799-1878). The picture for Elizabeth is that of a young woman. Elizabeth was well-past her youth when cameras and photographs were invented, so this cannot be her.

Tree of Jacob Vanderhoof, Ann Elizabeth Hopler, and sixteen children

I looked at the youngest offered child, Mary, born in 1822, when her mother was fifty. The only source is another family tree. This will not suffice.

Source for the life of Mary Vanderhoof is another tree

In 1848, Mary Vanderhoof and J K Odell married in Sussex County, New Jersey. This was just before state-wide registry was required; however, the event was recorded at the county level and can be viewed online. From this record we see that the bride was described as "of Wantage." This is in Sussex County, about thirty miles northwest of Rockaway Valley in Morris County, where Jacob Vanderhoof and and Ann Hopler had resided before their deaths.

On October 30, 1861 Mary Odel died in Vernon, Sussex County. This record is also available online. State-wide registration was in the form of ledger books at this time. The cause of death was consumption, or tuberculosis. Her parents were Jacob and Elizabeth Vanderhoof.

Mary Odell has a memorial page at Find A Grave, along with a photograph of the stone. She was buried at Deckertown Union Cemetery in Wantage.

The above-mentioned sources don't help us definitively rule Mary in or out as a daughter of Jacob Vanderhoof and Ann Hopler. Without visiting this cemetery in person, we can check for other Vanderhoofs buried there.

We find Jacob A Vanderhuff (1791-1870) and Elizabeth Swan (1793-1870) listed in the same cemetery as Mary. They seem more likely to be her parents. (Yes, Mary is listed as their daughter at Find A Grave. This is because I requested this change after finding and reviewing documents.)
