Hi.You seem to have found a second cousin of mine!I had the census data on John, but I never tried to find out more.If they haven’t already found it, her family would probably be interested in Peter O’Brien’s Civil War record and the County Wicklow records that I have. My Grandmother Anna “Annie” was in touch with her brother George until his death, but I never heard anything about John that I can recall. My mother, and the two of her sisters that I saw the most of, all knew “Aunt Jeanette”.She apparently was around the Hogan household in Brooklyn in their childhood years (1910 and after).She was referred to in conversation as Anna Oldfield Hogan’s “stepsister” and I think she was the primary source of their knowledge of William’s first marriage.Looking at your data, I am pretty sure that this is the same person as the death certificate.I am less confident of the 1900 Census, but it would be a strange coincidence to have another person come up with that collection of answers. The religion background is interesting on its own, but the main significance for our purposes is that Church of Ireland records are much more likely to produce something.I have had no luck finding Catholic church records for the Hogan line in County Kerry.Oldfield, of course is a less common name.The key would be to come up with names and dates.Then, there is the Canadian mystery. You have seen David’s posting?Whatever you think is OK with me.
