Hi Eva - I'm responding to your very old posting, so I hope you get this.
I know of your husband's grandfather, Cassius "Cash" Clanton. His second wife, Lulu Mildred (Birch) was my great grandmother. They married late in life and had no children together. They lived in Southern California and Cash died 2/1973 in San Gabriel, California, I believe. I knew of Wesley, but never met him, as my great grandmother died shortly after I was born and the families lost contact.
Do you by any chance know where Cash was born, or his exact date of death?
