Thank you Matt!
I could never link Paul Moran to my g-grandfathers family. However I believe you are correct that he is Joe's father, as I too keep running into his data. The story was that he and his brother left Bishop because the parents died. Also that there was property left behind in San Francisco , which for a boy could be a part truth to another story. He and Harriett (Etta) had 3 children. He and May had no children.
