I don't know if I can help? My father was delvin wayne black, my mother hazel Marguerite gibbons black. They divorced and he married fay black. My father was from Denton texas he had lots of relitives there also, california. Not sure how the caliifornia people were realted to him. He was in the dry cleaning business in california. He had a brother in Denton texas that was in the same business. He had another brother named George black in Denton, Texas he ran a movie threater their. maybe if the black family keep trying we may get lucky and make some connections? Good luck anyway.
