My honest answer to your question is, unfortunately, I don't know.
My Paternal Grandmother was Mary Tucker Rich
She died in 1959 when my Father was only 9 years old. Her husband, my Grandfather, William Carl Rich, having died a few years earlier, left my father an orphan with no knowledge of his heritage.
I have pieced together what I could find through public records to show that my Great Grandfather was James A. Tucker
Son of Gabriel Tucker. Beyond that, records are very scarce and my trail fizzles out. I would be happy to do some research on your Uncle Jim Tucker and his son Raymond to see if I can find any connection. Do you have profiles started for them?
