Thank you for the hints of info and trying for the military record. I don't know if this is him in the 1930 King County Census but his name is not common and the dates fit so you could have found him. I suppose a marriage record for Catherine E. might help too. who knows I might even have a mystery photo of her too in this box. well we will just have to keep snooping around. thank you for answering my post.
This man is my father's friend, I beleieve, because I found the photo/postcard in his box of belongings.
I am just so curious about my father and his life back then. I have been able to learn more by doing genealogy and looking into friends and neighbors. I posted this picture of his friend John C Klapp in hopes that his family might have some stories to share and I wanted to share this picture with his family (or others who might have served with him)
thank you again. let me know if you can link him to your family tree.
