I am creating a family tree for my children unfortunately I don't know very much about my Grandfather's family. He died when my Father was young. The only information I have is: Name- Francis Mahaney born 1911, his wife's name Catherine Ahern (born 1908). In 1930 he lived in Oswego, NY with his parents Patrick (born approx 1864) and Elizabeth (born approx 1867, maiden name Murphy),and his siblings Joseph (born approx 1897), John (born approx 1899), Elizabeth, Catherine (born approx 1902), Agnes, and Henry. Both Patrick's and Elizabeth's parents were born in Ireland. But everyone I have listed here was born in New York. I believe his sister Elizabeth's married name was Donaher. If anyone has any information I could use I would appreciate it. Thank you.
