Hello Tom,
Well, it looks like we're kin! My grandmother was Ruth E Pifer married to William R. Vogler. My Dad is their son Clayton William Vogler. You don't see much on the internet about him, because he's still alive and living with us! He'll be 92 in September. Of course I never knew Twila Mae, but Aunt Millie (and Uncle Jack Partridge, who was my Mom's brother) lived up behind Grandma and Grandpa Vogler, a half a block away from us in Ellwood City! Nice to meet you! I would love to collaborate with you. Don't have too much on the Pifers, and I'll share any info I have with you. I'm sorry it took me so long to answer, but I had begun to give up hope ever hearing from anyone on this thread, but thankfully you reached out! Hope to hear from you soon.
Diana
