More ONeil Cousins

We have another set of potential ONeil cousins.

Two people who are second cousins to each other share DNA with my father and his three siblings.

The common ancestors of these DNA matches are Andrew O'Neil, born about 1798 in Ireland and his wife, Bridget Goodfellow, born about 1798, possibly in County Cavan, Ireland. They settled in New York City in the late 1840s.

Household of Andrew ONeil and wife, Bridget.

In the 1855 New York State census, Andrew and Bridget resided in New York City with their five children, ranging in age from 12 through 22: Michael, Peter, Andrew, Margaret, and Patrick. Note that Michael O'Neil had been in the city for 11 years, while the rest of the family was present for six.

To work up these DNA connections, you need to find descendants of this couple in the DNA database. But- even if this couple has descendants in the DNA database, the connection is distant, so no detectable and reportable shared DNA may exist.

ONeil is a popular Irish surname with a variety of spellings. Over half a million people lived in New York City in 1855. (Today about 8.5 million people reside in Manhattan.) Tracing the marriages, children, grandchildren, and so forth of ONeils is tricky.

Margaret ONeil married Bartholomew Neville. When she died in 1907, she was widowed and childless. She left behind a will that was probated in Kings County, New York. From this will, we find out that she had another brother, Terence. He was not with the family in the 1855 census. More about Terence later.

Proved November 19, 1907 in Kings County, New York.

"Second. I have not mentioned my
brother Terence O'Neil's name in this Will
nor made any provision for him herein, for
the reason that I consider him well enough
provided for with his own property and poss-
essions."

Andrew O'Neil died in 1868. He was originally buried in Jersey City at Saint Peter's Cemetery in Section G South, plot 14. In 1885, Andrew, other O'Neils, and Murphys were removed to Calvary Cemetery in Queens, New York. (The Newark Archdiocese maintains an electronic database of burials at Find A Loved One Search.)

A brief notice of the death of matriarch Bridget appeared in the local paper The Sun in 1885. She was described as a "native of county Cavan, Ireland."

Obituary of Bridget O'Neil from the newspaper The Sun in New York City, July 4, 1885.
Note: July 4, 1885 was a Saturday. The obituary states she died on Saturday, July 3.

"O'NEIL. - On Saturday [Friday], July 3, Bridget O'Neil, aged
84 years, native of county Cavan, Ireland.
Funeral to take place from her late residence, 87 Washington st., on Monday, July 6."

Maybe Bridget's husband, Andrew ONeil, was also from Cavan. Some records survive for County Cavan in the 1800s. I looked for Charles ONeil and Catherine Brougham, the supposed parents of my third great grandmother, Mary Neil. I found a marriage record for Patrick Neal and Cath Brogan from 1824 in Urney Parish. Could this have been Mary's parents? More research is needed. Maybe the name is more commonly spelled Brogan and not Brougham.

More on Terence ONeil

To trace Terence ONeil, we cannot stop at the records available at Ancestry. Additional documents were filed to probate Margaret's estate. Some are available at FamilySearch.

Probate Administrator Records for Kings County, New York.
Available on FamilySearch.org Image Group Number 004362601.

"Administrator Records" provide several pages listing names and addresses of Margaret's relatives. Terence ONeil, her brother, lived at 153 Steuben Street in Jersey City, New Jersey.

Below is Terence's death certificate from 1910 and a picture of his gravestone in Holy Name Cemetery in Jersey City.

This DNA connection was only recently brought to my attention in the current year, 2026. Yet the dates on the records of Terence is from 2019.

Why did I gather this information seven years ago? Because Terence's son, Andrew Leo ONeill (1863-1941), married into my mother's family. My mother is not an ONeil descendant, but she has cousins who are.

Terence's third great granddaughter is among my DNA matches. She and I are third cousins, once removed on my mother's side. We share a segment of DNA. Ancestry does not report shared DNA between her and my father.

Note that Ancestry does not provide you a list of everyone who shares DNA with you. Both testing parties would need to upload their DNA files to GedMatch to check for shared DNA. Not finding someone listed as a DNA match at Ancestry does not mean that you don't share DNA.

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.

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.

Wedding Book from 1901

Thank you to the person who sent me this marriage book from 1901. (She found me through this blog. She was cleaning out an old desk.)

The marrying parties were Louis Kraus and Christine Zoeller. They married January 21, 1901 in Newark, Essex County, New Jersey. A letter was inside the book, providing additional details. The letterhead was that of First German Reformed Church at 31 Blum Street in Newark. This church is called Second (West) Reformed Church on the Old Newark website.

This is similar to an item that I received from the wedding of my great grandparents, Howard Lutter and Ethel Laurel Winterton. They were married in Newark in 1910.
