Looking for my biological grandfather's side of the family. All I know is that he was married to Lillian Curtis and the had 4-5 children. My biological father was MICHAEL JOSEPH COMERFORD, their son and then they had 3-4 daughters. I think their names were: MARY, JEAN, LILLIAN. I never met that side of the family cause my parents divorced when I was young. I just recently this past year found info on my biological father and since have met 2 of my half sisters that live in Chicago. There is one more sister to meet but all I have is that she was born in CHICAGO AROUND MAY/JUNE OF 1986 and her mother's name was Connie. I would appreciate any info anyone has.
