Kilcoyne's in San Diego; Cincinnati; Louisburg, Mayo...
I'm not a big geneaology buff, but browsing over the list included in this forum, I didn't recognize anyone from my "Kilcoyne line" represented...so here I'll add a bit (and I'll try to take the time to add more when I get my hands on our family tree).
My grandpa, Patrick Kilcoyne, married a fine Irish woman, Margaret Collins, and settled in Cincinnati, Ohio.They had 8 children (in true style!), their eldest being my father, James (aka. Jim...who may have submitted the Anthony entry, actually?!).Following my Dad (San Diego)are: John (Indiana), Bill (Ohio), Patricia (Connecticut), Rob (Ohio), Dan (Ohio), Margie (Ohio), and Tom (Ohio).My grandpa, Patrick, came from Louisburg, Mayo (consistent with others' reports here of Mayo/Sligo geography).His eldest brother was Anthony.He was also from a large family.Two of his sisters married Durkan brothers and their families still live in Louisburg, as do many of the Kilcoynes.Some of our other Kilcoynes in Ireland live in Limerick, Galway, and Dublin (and probably elsewhere as well?!).This probably isn't much help to anyone, but it'd be fun to have one of my near relatives find this entry and say hello ;)I'll try to input something more substantive next entry.
