Trying to get any leads on my Great Grandfather and Great Grandmother. John Monahan married Deli Mackin (about 1890-1900--Brooklyn NY) My mother has told me that John was from County Cork Ireland. John and Delia had 3 sons-(John, James and Robert(my Grandfather) and a daughter named Maud. Not sure where Delia Mackin was from or where she was born. Thank You--Mark
