Thank you for doing all that research. Some of it I knew, but others I didn't. Katherine was my mom, so this is how Donald is related. My mom passed away shortly after their divorce, so I never knew about him. I was only for at the time. Just trying to see if he had other family, such as kids or another wife. As I stated before, I can't find an obituary or burial site. This leads me to believe that he had no other family left.
