Thanks,KG!
If you or anyone else watching can trace James O'Hanlon Sr back to Armagh, I'd be very grateful. He was a soldier at the time of marriage in 1902. I've found plausible army records, but no definite link. Father given as James in their wedding cert.
I have the wedding cert, and a lot more info on the Grahams (and Sarah's maternal side, the O'Neills/Owens), but nothing on the O'Hanlons until their marriage. Also lack a lot of knowledge beyond 1922 - some info on who my grandfather's brothers and sisters married (names include Pimley, Pedlow, Morrow), but not a lot beyond that.
Particularly interested if anyone knows about John Henry O'Hanlon, or more info on the Weaver Street bomb (found the post on treasonfelony blog already), in which Henry and Martha O'Hanlon were injured, and Eliza O'Hanlon killed.
Thanks KG, thanks all!
