Hi Gloria,
I think we have the same John Creagh who fathered 23 children in common. According to the research I've done so far, John Kerin Creagh had a son named Stanley Gordon Creagh, who married Amy White Creagh, and had a son named James. They married in Michigan but then moved to Illinois.
John Creagh is also my husband's great great grandfather. We have recently come into contact with another one of John's son's family - Alfred Creagh.
I would love to touch base with you and possibly share some info.
Thanks!
Alma
