Tracking family that only appear together on 1940 census New Jersey, USA?
I am finally breaking down and asking for help on a brick wall in the family tree, I can only find an exact set of relatives in the 1940 New Jersey census. No other census years, or records listing them together. There are also a couple other similar people but their dates dont add up, and it looks like it has confused family trees and is making it difficult to work backwards. Any information, especially parents or birth/death/marriage records would be really helpful. Thanks for any help!
So here is what I have got:
Joseph A (possibly Aloysious) O Brien birth 8/2/1896, death 1978 New Jersey
possible parents: Francis X O Brien, Mary Longworth
Possible siblings: Mary A, and Margarete
in the military between August 6 1918 and September 30 1921
Ironworker maybe? Father possibly a Brass founder?
Catherine (possibly E, possibly Irene) O Brien, listed as 40 in census but death index records say birth 11/2/1904, death 1992 New Jersey
Marion R, born 1927 New Jersey
Joseph Jr, born 1929 New Jersey
Catherine, born 1931 New Jersey
Jean Ann, born 1933 New Jersey
Geraldine, born 1938 New Jersey
Issues I have found: There seems to be a marriage certificate for Joseph A O Brien and Catherine Egan in 1919 in New York, but wrong parent's name for Joseph.
Another issue: I found other 1920 census records for a Joseph A O Brien and Catherine Irene or Irene Catherine O Brien in New Jersey, but again puts her age wrong at birth date 1895, and also appears on the 1940 census with Joseph A O Brien with other kids in New Jersey. Some family trees listing his marriage to Irene Catherine do list his parents of Francis X and Mary Longworth though
One of these Joseph A O Brien appears on 1900 and 1910 census records with parents of Francis X and Mary Ann with the correct age and siblings, how do you tell which one? Or are both of them the same person and he had two families in 1940? It shows they lived like 10 miles apart
