You wouldn't happen to know if John had any siblings would you? My great grandmother was born about 1880 in Chicago and there is a family story that her father owned a restaurant in Chicago. I have conflicting documents about both her first and last name. Her first name has been listed as both Margaret and Lillian. Her marriage certificate has O'Hearn on the state part and Ahearn on the part filled out by the church. I know her mother was from County Claire, but that is about all. Your information just sounded very familiar. Thanks.
