Thanks for the reply.I think your dad was my grandfather's brother.It's too early in the morning to figure out what relation that makes us!!I also think you and I met at my grandfather's wake - Robert Emmet Donegan.
I have a little bit of info beyond what you know, which my grandfather ("Big Daddy") shared with me a few years before he died.I haven't really done any active research in the meantime.
James A. Conlon married a woman named Anne somewhere around 1800.My grandfather wrote "County Louth" next to these two, but I don't know if the marriage took place there, or if one or both were from there.
Their daughter, Mary Ann Conlon, married Owen F. Donegan.I believe they had three children - Patrick, Mary Ann (married name Morsell?), and Owen A. (1862-1911).
On the other side, Timothy Collins married Sara Halpin (~1830?).For them my grandfather noted County Clare, but again I'm not certain of precisely what he meant.
Their daughter Mary Elizabeth (1862-1928) married Owen A.Her sister Sara became a nun (Sr.Aloysius).
"Big Daddy" often mentioned that his grandfather was in the Civil War.I found a record for Owen Donegan enlisting as a private on Friday December 13, 1861.He was with "K Company, First Regiment Potomac Home Brigade Infantry."He was discharged as a corporal on Monday May 29, 1865 from "K Company, Thirteenth Regiment Infantry."
Unfortunately, you now know all that I do!I really haven't had the time to do any real research other than posting a few messages on the internet.I'd be happy to try to answer any question this message may have generated!Good luck!
