This was posted by my dad. Sadly, he passed away a few years ago, and I'm replying to the thread in case anyone reads it.
I did find that Effie's name was not Carmichael. Her name was Effie Ledoma Barton, and if you have any information on her, I'd appreciate it. My great grandfather was Harley Carmichael, a middle school principal in Indiana, and he and Effie never married. My grandfather was given up for adoption, and Effie later married a man with the last name Palmquist.
