My GGGrandfather, John Kenah, was born in Ballymacoda, County Cork, in 1826.
His father was Patrick Kenah. His mother was Margaret Cadigan, born 1804 on Cape Clear Island, which is part of County Cork even though it is an island off the coast. It is the southern most point in Ireland. There are 35 inhabited islands off the coast of Ireland.
John left for NYC in 1857. According to his personal papers his was father had died but his mother remained in Ireland. I have tried to follow up on Margaret, and think she may have remarried and gone to Canada, possibly Nova Scotia.
