Cora,
Thank you for sharing with me what you've found about our family! Yes, my Dad's name was Jay C. Miller & J.C. Miller was my Pappaw. I spent a ton of my childhood at Mamaw & Papaw's house on Elk Creek Rd. In West Middletown Ohio. I didn't know Daymond or any of the Miller's in Kentucky very well at all. I do remember going with Mamaw & Papaw down to Kentucky to visit his family but I was so little I have barely a memory of the trip.
Maybe it will always be a mystery but I think there's sufficient anecdotal evidence that from Alfred down our male biology is from the Back clan... Which I'm sure you've seen goes back to Germany where it was spelled Bach, & our ancestor was a very close relative to Johann Sebastian Bach!
BTW our first grandaughter was named Ivy Kora Miller... They went with the K instead of the C for some reason. lol
If you find anything else out, please share & I'll do the same!
Thanks, Chris
