Martin, Thomas
Thomas Martin (1840-1911), born in Scotland, was a pioneer in the Watsonville area along with four brothers. W. H. Martin may have been one of those brothers, but Thomas was not related to Edward Martin (also of Watsonville). According to a note under "Martin Bros." in the "Names on the Map" index, one of the brothers was named John Martin, but he's not the John Martin in this link. In 1882, Jack Swan wrote that he visited Thomas.
