I believe your logic is solid. ? My son and I were baptized with my mother¡¯s maiden surname, Ford, as our middle name. ? ?And I know of living O¡¯Shea distant female cousins living on Beara Peninsula with 6 of 8 Sullivan grandparents. ? Adjacent families intermarry in small townlands over multiple generations. ? ?Under British plantation era penal laws, having strong Gaelic clan surnames like Sullivan brought attention costing property grabs of livestock and land. ? ?I believe the multiple Keith matches under L270 could be former O¡¯Keefe Munster men who adopted Scottish Keith upon immigration, similar to what a McGill (icuddy) distant cousin told me.
