ONeil DNA Cousins

Have relatives of Mary Neil (1830-1898) been identified among the DNA matches at Ancestry?

Mary Neil, or Neill, or ONeill, was my great great great grandmother. She was born around 1830. On the record of her first marriage in 1847 to my third great grandfather, Calvin Cook (1826-1889), names of parents were not recorded. The names of her parents are from the record of her second marriage to Nicholas Keating (1825-1898) in 1892: Charles ONeill and Catherina Brougham. Mary's death certificate from 1898 only provides her mother's first name, Katie.

Only the names of Mary Neil's parents are known.

In contrast, Calvin Cook's ancestors are well-plotted at this point in my research. As a bonus, this was an intermarrying group with lots of descendants. As a result, I have hundreds of DNA matches who trace back their ancestry to the ancestors of Calvin Cook: Wiggins, Peer, Post, White, Vanderhoof, Stegers, Young, Hopler, DeMouth, Muller, etc.

Ancestors of Calvin Cook, mostly from Morris County, New Jersey.
They intermarried. Their descendants share more DNA because of this intermarrying.

DNA Strategy

This is the strategy for identifying relatives of Mary Neil amongst the DNA matches:

Mary Neil and Calvin Cook have around fifteen descendants in the DNA database at Ancestry. Use of the "Shared Matches" feature (only available for an additional monthly subscription) finds other relatives. These shared matches might be connected through Calvin Cook OR Mary Neil. If the shared match has ancestry amongst Calvin's ancestors, then the connection is probably not through Mary Neil.

A few people do not share matches with the Calvin Cook Morris County ancestry. These are potentially related through Mary Neil's ancestors.

One of the problems is that we are working with tiny segments of DNA that trace back at least six generations. If we land in Ireland, there are few written records to demonstrate a relation.

DNA Matches of Interest

We will look at three people who match descendants of Mary Neil and Calvin Cook, but do not match anyone in the Morris County group. There are more matches who fit this scenario, but they have cryptic usernames, no trees, private trees, scant trees, and do not answer messages.

All three matches share less than 20cM of DNA with my group, or about one small segment of DNA. This indicates that the relation is likely third cousin or more distant.

The sorting feature places the DNA match's matches at the top. (Also a paid feature.) This is such a helpful mechanism for figuring out how relations relate to one another.

We will label the three matches as Person 1, Person 2, and Person 3. Person 2 and Person 3 are siblings. Person 1 turned out to be their second cousin.

Their common ancestors are Hugh ONeil (1835-1888) and Margaret ONeil (1838-1906) of Ireland and Washington, United States. (Washington became a state in 1889.) Person 1 descends from their son George. Person 2 and Person 3 descend from their son Charles.

Household of Hugh ONeil and his wife, Margaret, in the 1880 census.
Washington Territory, United States of America.
Children: Evelena, Minnie, John, Charles, Francis, George, and Kate.

Having the same surname as Mary Neil is great, but this is a common Irish surname and means little until we have paper documentation. Spoiler alert: we do not have any records connecting them at this juncture.

Hugh ONeil was a veteran of the Civil War. He died in 1888, the year before Washington became a state. His death record was a line in a ledger book. His parents were not listed.

Margaret ONeil died in Oregon in 1906 while visiting her children. Her death certificate provides the names of her parents as James ONeil and Margarete, last name unknown by informant, G W ONeil.

Was Margaret also ONeil? The records of her children provide no other surname. Some of their records are easily viewable online, such as marriage, death, and Social Security Death Index. No surname other than ONeil or ONeill was given for their mother.

Yet her memorial page at Find A Grave provides Cook as her birth name. Hmmm.

Cook is a common name. My Cook ancestry is Dutch, not Irish. The name was Van Der Koeck.

Future Research

More DNA connections will appear with new leads.

More records will find their way in an easily accessible format online.

I'd like to see Brougham turn up amongst the matches.

Private Charles Y Cook, Civil War Veteran 1833-1913

Charles Cook (1833-1913) was born in Morris County, New Jersey to Stephen H Cook and Elizabeth Vanderhoof. He served in the Civil War (1861-1865) with Company L, 27th New Jersey Infantry from September 1862 through July 1863 for a total of nine months.

Various Acts enabled Charles to file for a pension and increases. The pages in this packet reveal further information about the family. I was hoping that his pension would help link him to his great grandfather, Conrad Hopler, but not so. The issue at this point in the research is finding documentation that Charles' mother, Elizabeth Vanderhoof, was the daughter of Jacob Vanderhoof and Ann Hopler. Conrad Hopler, who served in the Revolutionary War, was the father of Ann.

If you can obtain an application for a pension for service in a war, you should do so. Anything could be in that file.

This pension record was ordered through Civil War Records. The price was $110 and the turn-around time was one month. The actual pages are in the custody of the National Archives.

Charles died of dysentery after a trip to Gettysburg, Pennsylvania, on July 11, 1913. He attended a fiftieth commemoration and died of an infection he survived fifty years earlier during the War. He was honorably discharged on July 2, 1863, which was in the middle of the three-day Battle of Gettysburg. His papers do not list this location or Battle as one that he participated in.

This cemetery is where Conrad Hopler (1730-1816) has a gravestone. I am seeking documentation that Conrad Hopler is a great grandparent of Charles Y Cook.

Stephen Cook and Elizabeth Vanderhoof married in 1819. They had at least five children:

-Ann M Cook (1820-1868), married Jesse Lee (1818-1888)

-Silas Cook (1825-????) (only mentioned in the books of Louisa Caroline Freeman Hickerson)

-Calvin Cook (1826-1889), married Mary Neil (1830-1898)

-William Henry Cook (1828-1902), married Emeline Young (1834-1906)

-Charles Y Cook (topic of this article)

Five children of Elizabeth Vanderhoof and Stephen Cook
identified by Ms Hickerson in her book, Vanderhoof.

I am missing at least one source of Ms Hickerson's research. I have found nothing about Silas Cook, born March 3, 1825, outside her mention.

Charles was able to claim a pension in 1890 because of service-related disability and in 1907 because he lived long enough. A card index exists. Charles has two different cards. The one at Ancestry reflects only the 1890 claim for disability. The card at Fold3 reflects both claims.

The family bible is mentioned in Charles' sworn statement from 1904. "He having been born on the 27 day of August eighteen hundred and thirty three- that his mother's family bible which is in the possession of his brother's widow contains the entry of which the following is a copy." This would have been Emeline Young (1834-1906), widow of William Cook. They had at least ten children. Who received the bible of Elizabeth Vanderhoof? I need it.

Pension file of Charles Y Cook. He mentioned his birthdate as written in his mother's family bible.

Charles clarified his name. "He always understood that he was named after a relative Charles Youmans by name but that his mother did not use the 'Y' in naming him and that he only took up the use of the 'Y' himself after reaching the age of twenty years and [illegible] did so in order to distinguish himself from others having the name of 'Charles Cook'."

First, thank you, Charles, for realizing that so many men bearing the name Charles Cook would confuse researchers for centuries. This has been my experience in researching COOKs.

Second, thank you for clarifying that you used the middle initial 'Y' and the middle name 'Youmans' and that this name was a relative's name.

Who was Charles Youmans? Charles Elmer Youmans (1809-1864) married Anna Cook (1808-1897), a paternal aunt of the younger Charles Youmans Cook.

Charles explained his family of creation. He married Sarah Lavinia Merritt in 1861. They had at least five children. I'm not sure if they had two sons named George Cook.

Charles Y Cook's listing of his wife and children

The children of Charles Cook and Sarah Merritt were: Laura, Mary, George, Phebe, and Samuel.

In First Presbyterian Church Cemetery with Charles and Sarah is a stone for George, engraved with a date of death January 6, 1866, aged two years, three days. This would give a birth around January 1864. So Mary could not have been born May 12, 1864. The pension lists George's birthdate as October 4, 1866. This could be a second son named George Cook, named after the baby who just died. There was no child named George living with this family in the 1870, so perhaps the second George also died early. Or there was only one. This remains unclear.

Sarah Merritt was also a Wiggins descendant. More research is needed on Wiggins. She and Charles Cook were probably cousins.

Daniel A Wiggins submitted an affidavit to support Charles Y Cook's application for an invalid pension. His age was listed, which is not usually seen in older records. Looks like 47 or 49 years old in 1891. This could be David Alvin Wiggins (1845-1927). He was a second cousin of Sarah Merritt, sharing great grandparents Jonathan Wiggins (1763-1815) and Phebe Fordham (1764-1851).

Charles wrote his occupation (brakeman, unable to perform because of illnesses contracted from war) and residences. He lived in Brooklyn, New York from 1884-1888. This explains the birth in Brooklyn of his granddaughter, Laura Bidgood (1884-1952), and his appearance in the Brooklyn city directories.

"then in Brooklyn, NY from 1884 to 1888 . . ."

"4 years in Brooklyn from 1884 to 1888 all the rest of time in Rockaway Township, Morris County, New Jersey."

-We still do not have a record supporting that Jacob Vanderhoof and Ann Hopler were the parents of Elizabeth Vanderhoof, wife of Stephen Cook.

-What other sources was Ms Hickerson using in her research of Vanderhoof and Cook in Morris County, New Jersey?

-Where is the family bible of Elizabeth Vanderhoof? In 1904 it was in the custody of Emeline Young (1834-1906), widow of William Cook.

Thank you, Charles Youmans Cook, for your service during the Civil War.

Tangled Family Lines at First Presbyterian Church Cemetery, Rockaway, New Jersey

On May 9, 2026 I visited the First Presbyterian Church Cemetery in Rockaway, Morris County, New Jersey. It was a rainy day, so the stones were darkened. I prefer overcast, dry days for cemetery visits, but this is how the schedule worked out.

This is an active church and cemetery. This is their website.

I saw some Wiggins stones. More articles on Wiggins are coming.

Two different Peter VanDerHoofs who died in 1913?

In the Rockaway Valley United Methodist Church Cemetery is the gravestone for:

Betsey M his wife (1846-1902) [born Hiler]

Clara (1861-1862)

Asa their son (1864-1902)

Note that the stone is etched with years and not months and days. The memorial page at Find A Grave has Peter's date of death as May 26, 1913.

In the New Jersey State Archives, I found a death certificate for Peter Vanderhoof. The date of death on this record was July 13, not May 26. This Peter died at the Odd Fellows Home in Ewing, Mercer County and was buried in Rockaway Valley.

Death certificate of Peter Vanderhoof
died July 13, 1913 in Ewing, Mercer County, New Jersey

Is this the death certificate for the Peter on the gravestone? The age, 67 years, is almost identical. Widower is consistent. Across his many records, Peter, husband of Betsey, is not listed as the occupation "teamster." No family members are listed on this death certificate. The informant seems to have been an employee of Odd Fellows Home.

In the newspapers for the Ewing area and for Morris County I did not find a notice of death or obituary.

What was the source of the precise date of death on the Find A Grave memorial? I don't know. I can't find it. I'm not saying that it doesn't exist, only that I have yet to come across it. The year could be wrong on the stone. This happened with Hila Vanderhoof (1803-1888) in this same cemetery. She died in 1888, but the year on the stone is 1886.

There is a transcription of grave stone inscriptions for this cemetery. Only the years are provided for Peter.

I found Peter and Betsey's stone in the cemetery. There were no flat stones or other markers to clarify the date of death. Sometimes members of Odd Fellows carved "F L T" inside links on the gravestone. Friendship, Love, Truth. I did not see this on Peter's stone.

Conclusions

Are these two separate men named Peter Vanderhoof who lived in the same area at the same time? Possibly. I have sixty men named Peter Vanderhoof in my tree.

The death certificate is proof of the precise date of death. The information on Find A Grave is not. But the death certificate does not link the decedent to his larger family, so we cannot be sure who he is.

Reuben Levy Bishop (1805-1856) was my fourth great grandfather. He died in Morris County, New Jersey. I have not uncovered his parents yet.

There was another man living in Morris County also named Reuben Bishop. His records, alongside my known Reuben, were discussed in this article. (The first name is usually written as Ruben, Reuben, or Rueben.)

Modern technology has brought us Full Text Search of records. In the past, the creation of an index of a record set might only include the name of the subject of the record. Full Text Search enables a search of any word in the document.

I've been told that Morris County probate records, although digitized by Family Search, cannot be viewed from home because of contractual restrictions. I visited the Morris County Surrogate's Office last year to locate a will from 1782 that was not filmed. Nobody could locate the films from this time period. I asked to speak with someone who could address the issue with access through Family Search. I was told, "We want people to visit us and view the films here." (I found the skipped will at the New Jersey State Archives.)

While logged into a Family Search Center computer, I searched for Reuben Bishop in Morris County. He witnessed three wills:
-John Woodruff in 1816
-Joseph Wheaton in 1824
-Josiah Goff in 1826

Note: these are poor quality images because these are restricted records, meaning you cannot download them. Compare these to the images of Reuben's will below, which were printed from microfilm at the Morris County Surrogate's Office years ago.

I looked into these three people. They appear to have been neighbors of Reuben in Chatham.

The Reuben who signed these documents was not my Reuben. My Reuben was born in 1805, so he was too young to begin signing in 1816. The signer was the other Reuben.

This other Reuben signed his own will on January 30, 1829. The will was proved September 21, 1829, indicating that he likely died in September 1829.

The family mentioned in this 1829 will were Reuben's brothers: Calvin, Luther, Miles, and Abner. No wife and no children were mentioned.

These names are not rare, but they are more unusual, especially as a group of five Bishop brothers.

The pertinent information from this index:

Reuben Bishop was a doctor of Bottle Hill. He died September 11, 1829 at the age of 58 [say born in the year 1771]. He was from Woodbury, CT [Connecticut].

Bottle Hill was the name of the area renamed Madison in the 1830s. Madison was a village within Chatham Township. This tracks because Reuben Bishop appeared on the tax ratables for Chatham in 1814.

Reuben Bishop was taxed for a horse.

The other location mentioned in the newspaper index is Woodbury, Connecticut. Dr Reuben Bishop has a memorial page at Find A Grave for South Cemetery in Woodbury.

A respectable physician & an honorable man.

The etching at the top of the stone appears to be a weeping willow over an urn.

A book about the descendants of John Bishop, a founder of Guilford, Connecticut, was published in 1951.¹ Dr Reuben does not seem to appear in this book, but a cluster named Miles, Calvin, and Luther does appear- and they lived in Woodbury.

A book that possibly pertains to Dr Reuben Bishop's family

In this book, we see three of the names mentioned in Reuben's will from 1829: Miles, Calvin, and Luther. Miles was the father and Calvin and Luther were sons of Miles. Below is this family arrangement linked to their memorial pages on Find A Grave. They were buried in Woodbury, Litchfield County, Connecticut.

Miles Bishop (1739-1815) and Sarah Chapman (1737-1822) had two sons:

-Calvin Bishop (1761-1834)

-Luther Bishop (1763-1850)

It is possible that Dr Reuben Bishop, born circa 1771, was also a child of this couple. He and the other two brothers, Miles and Abner, are not mentioned in this book.

Was Dr Reuben Bishop, originally from Connecticut, related to my fourth great grandfather Reuben Levy Bishop? Why did Dr Bishop move to Morris County, New Jersey?

More research is needed.

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.
