Marcial Sanchez was a member of Anza's 1774 expedition to find a route from Sonora to California. His wife was Vicenta Azedo. Does anyone have any ideas what the origins were for those soldiers? I am leaning away from Sanchez being indio but figure my choices are-from the south ie Alamos or southern Sonora, the Chihuahua (Janos and south) area and possibly New Mexico. Has anyone here had any luck in finding the origins of ancestors in those northern presidios of Sonora pre-1775? I have been doing autosomal testing on this line but need more clues.
