Please know this upfront though, that this may not be perfectly correct information.
My father, who I have obtained this information is 76 years old and his memory has begun to fail him.
I was just working on our family genealogy with him this weekend.
There has been a block at to his Grandmother Bullock's side. We were working on this.Her name was Ophelia Bullock. He cannot remember anything except this: He said he had an Uncle Toal.He believes that his mother was a Rials before marrying Bill Bullock. He remembers a RE or "Aury".I wasn't sure of the spelling.
He also remembers a Jess Rials.He thinks that Jess was Ophelia's brother.
I hope this helps, and I hope it isn't a false lead.Just sharing the information.
I'm stuck on this until I can gather something more solid.
