Hi Ken,
I look at your tree and it is correct that he was born in Mingo Junction Ohio. If you look at his marriage certificate you will see Mingo Junction stated as place of birth. I have a college paper of his that he talks about Mingo Junction and leaving it on a train for Cleveland. I will get that scanned for you.
I have been able to trace our Bowman ancestry to Switzerland. They came here around 1700 looks like due to religious reasons.
Best,
Jill B
