William may have married twice and lived with his second wife in Palo Alto, California for a time. In his will he leaves 1/2 his estate to his niece, Mary Adam Mitton of Palo Alto. He was separated or divorced from his first wife long before her death in 1929.
Do you have information on his second wife? I don't know her name or where she was from. It may have been Helen from Brechin?
Thanks for responding.
