Ok I've found some more information. I got Cornelius Gavin's cemetery records. He was born in Minnesota. His parents were Thomas Gavin & Mary Kelty (keltif?). His parents Thomas and Mary were both born in Ireland. Cornelius married Mary Heymann (daughter of William Heyman & Bertha). Mary was born in LaCrosse Wisconsin. I know that Cornelius lived in LaCrosse Wisconsin for quite a few years. His parents Thomas & Mary Gavin must have come to America since Cornelius was born in Minnesota. If anyone has any information on them I would be MOST greatful.
