I am matching GARRITY in the family finder test at FTDNA.com. My known ancestors in Co Mayo are FORD, MEARS/MAIRS, MANLEY/MUNNELLY, FOY. I also match GALLAGHER, JENNINGS, BROWN, COX and others. I am told by people in Mayo today that virtually everyone who came fr there with a common surname is related, because the pop was so small. Most people either died or left due to famine & TB. My ancestors were married in Ballina, Co Mayo in 1831.
