In spite of the mention of his WWII service, I don't see his draft registration at Ancestry. I also searched the Electronic Army Serial Number Merged File at NARA and didn't find him listed there.
I think that Paul Baysinger, Clarence's dad, was my grandmother Anna's brother. So Clarence was my mother's first cousin, and I don't think she ever got the chance to meet him. After Anna married Harvey McBee and my mother was two years old, they moved to Alberta Canada. As far as I know, she only came back to Iowa once, about 15 years ago.

I welcome additions and corrections, and would love to hear from all relatives.
