Looking for information on Cornelius Hayes born in 1884 in Iron Mountain, MO to Michael and Mary Hayes. Mary's maiden name was Halloran (sp?). Cornelius was, supposedly, one of seven children although there's only record of one, Patrick. Both Patrick and Cornelius worked for the railroad in the early 1900's. Cornelius was president of the Meatpackers Union and ran for an IL congress seat. He married Theresa Young and had three children - Leo, James and Helen. He resided in East St. Louis, IL - just outside of St. Louis Mo - until his death in 1964. Looking for ANY information on Cornelius' family (parents and siblings).
