My grandmother was Elizabeth Katherine Sullivan. She had a brother Patrick, James, Margaret, Mary, Elizabeth (who died around 1yrs. old, bitten by a black widow spider in her buggy and Katie who died in child birth. Their mother was Bridget Garvey who married Patrick Sullivan. Bridget's mother was Nora Hickey who married a Garvey.
I do have a second cousin named Thomas Sheehan and I'm not sure but I think his father was Jeremiah.
Thanks for any help
