I have nothing new at this time, but if I do come across anything, I will certainly let you know.
In the last month, I bought a 4 generation photo taken in 1920. It included Alwilda Barker Hiler (wife of Francis), her daughter Alta Hiler Stone, her granddaughter Ailene Stone Steinbaugh, and her one year old great-grandson. I found the baby alive and well at age 86 and returned the photo to him. He is a genealogist as well. I will send him your email address. He may have something that may help you.
