I believe my Granville's are the same. I have them going back to the mid 1800's. My great great grandmother was Annie
O'Donoghue who's Dad was John. She married Michael
Granville from Ballyaglisha. Michael and Annie had several children, Michael, Robert, John, Sara, and Mary, (My great grand mother, she married William
Adams from
Dingle). I believe it was Robert that stayed in Ireland to tend the farm and the others came to the US. If any of this connects, let me know and we can figure out any missing links.
