Question:

Does anyone know a "Martin Alexander Davis"?

All I know is that he lived in California about 40 years ago. He may still be there somewhere, I don't know. He's my paternal grandfather . . .

Best Answer - Chosen by Asker: I am assuming you do not know if your grandfather is alive or dead. Other posters have given you suggestions of where to look if he is alive. If you wish to ascertain if he is deceased, go to the Social Security Death Index (link below), and put his name in the search engine. If he is there, it will give you the year he died and where he last received Social Security (if he died before getting it, it will show where the check went to the survivors).
