Apparently John "Sean" Culkin that I need to find was born to Larry Culkin and ? Mary Miles.
Sorry should clarify that I have John married to Bridget Connolly and had 9 children born with first 2 passing very young.
I believe Bridget's parents maybe Patrick Connolly 1846 and Anne McDonnell 1852.
It is the Larry and his spouse I cannot find nor if there were any siblings for John.
Thanks again
