We are trying to find out more about my husband's g-g grandfather Thomas Crotty, b. 1827 in Shanagarry North, County Cork, Ireland; married Mary Boozan/Beausang in Cork in 1857 and emigrated to the US with four of their seven children in 1884. Thomas died in Somerville, Massachusetts about 1885; Mary died there in 1909. We are hoping to trace Thomas's family in Ireland. Possibly his father was a John Crotty living in Shanagarry, County Cork; the Crottys were said to have come originally from County Waterford.
