By 1920 he was head of a household in Jersey City Ward 2 with his wife Mary, also Irish-born, and two children — Mary, eleven, and Gerard, nine, both born in New Jersey. He had no sources at all in this archive before that sheet was read.

Life
Patrick O’Connor appears in our family tree as an Irish-born man, reportedly born in 1877. The tree names Mary Condon as his wife and Gerard O’Connor, Mae O’Connor, and Mary Arata as children, but this archive supplies no independent record confirming his dates or relationships.
He was in this archive twice — once documented from the 1920 census of Jersey City, and once as an unresolved man 'reportedly married to Mary Condon and father of Gerard and Mary/Mae', which is this man and these children. Merged on 9 August 2026.
How we know this: Very weak: the birth and family relationships come only from a family-tree entry. [1][2][3]

Bayonne and the Industrial Waterfront, 1870–1920
The Bayonne in these family records was a new city built around water, rails and heavy industry. Bayonne Township was formed only in 1861, uniting older settlements on Bergen Neck; it became a city in 1869. The…
What Sponsors and Witnesses Can Tell Us
Catholic registers often preserve the people standing just outside a family photograph. A baptism normally names the child, parents, date and sponsors or godparents; a marriage normally names the couple and wit…
Reading Irish Civil Registration
The year 1864 is the dividing line in this family’s Irish paper trail. Civil registration began in 1845 for non-Catholic and civil marriages, but from 1 January 1864 the law required registration of all births,…
Farmers and Labourers in North Cork
Two words in the Cork records—“farmer” and “labourer”—describe different positions in the same rural economy. When John Fitzgerald married Margaret Fraher at Kildorrery in 1870, the register called John, his fa…

Islandeady is not an island off Galway. It is a rural parish between Castlebar and Westport in County Mayo, set among lakes and low hills in the shadow of Croagh Patrick. That distinction solves a long-standing…

What we still don't know
- His exact birth date and place
- His parents
- His marriage date and place
- Independent confirmation of his wife and children
- His occupation, residences, and death
- [HE WAS HERE TWICE] A second **Patrick O'Connor** stood in this archive as *'an unresolved Irish-born man reportedly married to Mary Condon and father of Gerard and Mary/Mae'* — which is this man, with these children. The two shared a wife and were merged on 9 August 2026 by the new same-spouse test.
- His parents, who are unnamed anywhere. The 1920 census establishes only that both were Irish-born. His 1900 arrival gives a passenger list to search, and a naturalisation would name his townland.
- [IDENTITY — TWO WIVES, ONE CENSUS] This archive records Patrick with **two** wives, `mary-condon-1882` and `mary-o-connor-1878` — the latter being Mary Condon, born 11 July 1878 at Flemingstown, County Cork. The 1920 census shows **one** wife: Mary, aged 38 and born in Ireland. An age of 38 in January 1920 points to about **1881-2**, which fits the first record and not the second, though both women are Irish-born Condons and the two entries may well be one woman with two competing birth years. **Nothing is merged**; the census is recorded as evidence and the question stays open.
- [IDENTITY — ONE DAUGHTER, TWO RECORDS] The census shows a single daughter, Mary, aged 11. This archive holds both `mary-arata-1908` (born 3 May 1908) and `mae-o-connor-1909` (born 4 July 1909), each already flagged as a probable duplicate of the other and each married to Peter Arata. **The census supports one daughter, not two** — which is evidence for the duplication, though it does not settle which birth date is right.
