Thanks so much for getting back to me. That my grandfather William was biologically connected to the Goodwins has always been what my mom(his daughter) and I have thought. It seems that anyone who may have known for sure is now gone, but I would still like to try to find out. I can see from the US census data that Salome, my grandfather William and his brother Ken lived with Salome's daughter and their sibling Hattie and her husband Harold McKenzie after Salome's husband William died.
If you come across that photo I would love to see it.
Take care and let me know if come across any other information about my grandfather in your research.
