Children of Daniel and Elizabeth; Eleanor b. 1915, Dorothy b. 1916, Daniel, jr. b. 1918, Richard b. 1920, and James b. 1924.
Daniel, jr m. Jessica S. Trefry. Also far as I know Daniel and Jessica died in Bellerica, MA. in 1990 and 1974 respectively.
Timothy Canty came to Boston from County Cork with his mother, Mary, and brothers and sisters. I don't know the date when they immigrated. I can only assume it was some time after 1854 because Timothy was born in County Cork, or so the story goes.
