Mary Vanderhoof 1801-1853 and Mary VanFleet

Was Mary Vanderhoof (1801-1853) a daughter of Jacob Vanderhoof (1772-1847) and Ann Hopler (1772-1841) of Morris County, New Jersey?

Yes, according to her gravestone and a published genealogy.

Below is a picture of Mary's gravestone, located behind her parents, in the DeMouth Burial ground in Denville.

Gravestone of Mary Vanderhoof, died August 31, 1853.
DeMouth Burial Ground is located on private residential property.
Please be mindful if visiting.

The inscription is difficult to read today. It appears to be:

Mary

Daughter of

Jacob Vanderhoof

Died Aug 31, 1853

Aged 52 years

In her book Vanderhoof (1991), Louisa Caroline Freeman Hickerson identified Mary as the third child born to Jacob Vanderhoof and Ann Hopler.

Other than this gravestone and the mention of this gravestone in Ms Hickerson's book, there is no other proof that Mary Vanderhoof existed.

No death record was found for Mary Vanderhoof in the New Jersey ledger books covering 1853, in spite of the precise date on her stone.

Mary remains unidentified in the 1850 census. Both her parents were deceased by this time, so she would have appeared in her own household or in the household of a sibling or other relative.

Mary VanFleet

Ms Hickerson raised three questions after the short blurb about Mary Vanderhoof's gravestone. The issue concerned the surname VanFleet, arising from Jacob Vanderhoof's estate.

Jacob died intestate in 1847. His debts exceeded his assets. There was no money to to distribute to his immediate relatives, which would have provided a listing of his children and/or grandchildren.

Jacob's assets were listed and tallied in 1848. The final line of his assets was "Money collected of Mary Vanfleet 3.00." Below is the image of the accounting that Ms Hickerson wrote about.

"Money collected of Mary Vanfleet 3.00"

Who was Mary Vanfleet and what was her relation to Jacob Vanderhoof? No information about this Mary VanFleet is provided in Jacob's estate papers, such as her age, residence, or husband, if any. 

VanFleet had various alternate spellings, such as VanVleet, VanFliet, VanVliet. Also the "Van" could be removed, resulting in more variations.

There was no shortage of people named Mary VanFleet in the 1840s living near Jacob Vanderhoof.

Below is the image of the marriage record referenced by Ms Hickerson. On September 16, 1826 Mary Vanderhoof married William VanVliet "both of the township of Pequanack." True to most of the marriage records for Morris County, New Jersey in this time period, the names of parents and ages are not provided.

I certify that on this Day I married Mr William
Van Vliet to Miss Mary Vanderhoof both of the township
of Pequanack in the County of Morris & State of New Jersey.
Barnabas King Minister of the Gospel."

Was Mary Vanderhoof, wife of William VanVliet, related to Jacob Vanderhoof? We cannot tell from these records alone.

The third record Ms Hickerson mentioned was the 1850 census. In the household of Elijah Vanderhoof was Jacob Vliet, age 15. Below is that image from Pequannock.

1850 United States Federal Census: Pequanac, Morris County, New Jersey.
Elijah Vanderhoof, age 24, farmer.
Amanda, age 21.
Alison, age 8 months.
James VanDuyne, age 24, labourer.
Elijah, age 20, labourer.
Jacob Vliet, age 15.

The head of this household, Elijah Vanderhoof, was a grandson of Jacob Vanderhoof and Ann Hopler. His parents were Peter Vanderhoof and Rachel Peer. How was Jacob Vliet related? We do not know with the limited information offered in the 1850 census.

Who were the VanFleets?

On the same page of the 1840 census for Pequannock are the households of William Vanfleet, Stephen H Cook (husband of Elizabeth Vanderhoof), and Jacob Vanderhoff. Age ranges for males and females in the households are ticked, but that is as detailed as a census prior to 1850 will offer.

Pequannock, Morris County, New Jersey

Household of William VanFleet: 7 people in the household. Oldest male between 40-49. Four males below age 15. Oldest female between 30-39. Other female 10-14. Did this household contain Mary Vanderhoof as the matriarch? We cannot tell from the 1840 census.

Some Death Records and Few Details

William VanFleet died November 6, 1853 "near Stan Hope." He was 61 years old. His parents names were Peter and Sarah. He was born in Somerset County.

William Vanfleet died November 6, 1853.

Mary VanFleet died June 9, 1851 in Morris Township. She was 61 years old. The names of her parents were not given.

New Jersey. Marriages and Deaths Morris County Volume Z 1848-1867.
Mary VanFleet died June 9, 1851.

We do not know if this death record is for the same Mary VanFleet mentioned in the estate papers of Jacob Vanderhoof in 1847.

We do not know if this Mary VanFleet was born a Vanderhoof.

We do not know if this Mary VanFleet was married to William VanFleet.

Conclusions

We should accept Mary Vanderhoof, died 1853 and buried near Jacob Vanderhoof, as his daughter. The only proof is their relationship inscribed on her stone, but this is more than most of his theorized children.

Jacob probably did not give the name "Mary" to two daughters who both survived. Mary Vanderhoof, wife of William VanVliet, could have been a sister or cousin.

The Mary VanFleet who paid $3.00 to the estate of Jacob Vanderhoof may or may not have been a Vanderhoof. We simply do not know within this context how, if at all, Mary and Jacob were related.

Maria Vanderhoof Tucker 1807-1879

Research Question

Was Maria Tucker (1807-1879) a daughter of Jacob Vanderhoof (1772-1847) and Ann Hopler (1772-1841)?

Published Book

In her book Vanderhoof (1991), Louisa Caroline Freeman Hickerson did not list Maria Vanderhoof, wife of Charles Tucker, as one of the children of Jacob and Ann. If she was born around 1807, there was room for this birth between John in 1804 and Charlotte in 1809.

Children of Jacob Vanderhoof and Ann Hopler (with notation that any might be in error and some children may be omitted):

1. Peter (1797-1847) married Rachel Peer (1800-1850)

2. Elizabeth (1799-1878) married Stephen H Cook (1797-1853)

3. Mary (1801-1853) probably unmarried

4. Hyla (1803-1888) married William Cook (1801-18xx)

5. John (1804-1888) married Sarah Dobbin (1805-1876)

6. Charlotte (1809-1886) married Chilion Cook (1807-1888)

7. Samuel Saron (1811-????) married Eleanor Anderson (1815-????)

8. Richard Vanderhoof (1814-1892) married Eliza Cook (1810-1875) and Jane Tunis (1832-1919)

9. Conrad (1817-1874) married Mary Hopler (1823-1903)

Family Trees

Find A Grave and family trees posit Maria Vanderhoof as the wife of Charles Canfield Tucker (born about 1805). Imaged below is an example of one such tree.

Other Women Named Mary

A prior article discussed Mary Vanderhoof (1822-1861), wife of John K ODell (1824-1898). I determined that she was not a child of Jacob Vanderhoof and Ann Hopler. A future article will discuss Mary Vanderhoof (1800-1853) and Mary VanFleet.

The Vanderhoof family includes multiple women named Mary or Maria in overlapping generations. This article focuses only on Maria Vanderhoof, wife of Charles Tucker, and does not assume that she is the same Mary Vanderhoof who died in 1853 or the Mary Vanderhoof who married a man named VanFleet.

Records of Mary or Maria Vanderhoof, Wife of Charles Tucker

New Jersey did not begin registration of births until 1848, well before Maria was born. A baptismal record would provide the name of her father and probably her mother, but this record has not been identified yet.

Marriage records of the 1820s were created by the religious officiant and filed with the County of Morris. Such records did not usually provide names of parents, but this would at least confirm that Charles Tucker married Maria Vanderhoof and not Maria with another surname. As of this writing, I have not found a marriage record in Morris County in the 1820s for Mary Vanderhoof and Charles Tucker.

Maria's first chronological appearance in a record was the 1850 federal census, the first to list all members of households.

Below are snapshots of Charles, Maria, and their children from the 1850 and 1870 census entries for Rockaway Township. She was 43 in 1850 and 63 in 1870, which is consistent with being born in 1807.

Charles Tucker and Maria were last seen in the 1870 census. I have not found a record of the death of Charles. A gravestone has not surfaced.

Maria was buried at Rockaway Valley United Methodist Church Cemetery in Boonton. Many Vanderhoofs were laid to rest here. Maria's stone gives her date of death as September 13, 1879, age 72 years, 7 months, and 17 days. The calculated date of birth would be January 27, 1807. This date of death does not correspond with an entry in New Jersey's index of deaths. A death certificate would be another chance of seeing the names of her parents. Imaged below is Maria's memorial page on Find A Grave.

for Maria Vanderhoof Tucker (1807-1879)

Maria Vanderhoof and Charles Tucker had at least eleven children from 1829 through 1851: Peter Vanderhoof, John, Elias, Mary Etta, George Allen, Charles, Marinda, Helen Elizabeth, Laura A, Agnes, and Sarah Jane. They probably had other children who died early.

To indirectly catch Maria's birth name, we can look at the marriage and death records of her children. I found only one record that identifies Maria, wife of Charles Tucker, as a Vanderhoof. Their son, Elias, died November 25, 1913 at the New Jersey State Hospital in Morris Plains. This is locally known as "Greystone" and still exists today for inpatient treatment of mental illness. The death certificate of Elias Tucker provides his mother's name as Maria Vanderhoof. Below is the image of Elias' death certificate.

Elias Tucker (1833-1913) was one of the older children of Maria and Charles. In 1860 he married Phebe Elizabeth Blanchard. He served in the Civil War.

Conclusions

None of these sources provide the parentage of Maria Vanderhoof. More information is needed to link Maria to any parents.

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

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
visited on the cold day of November 11, 2025.
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.
