My ggrandmother name was Carmen Duarte from Sonora she married Jose Angel Mendoza. They moved to Yuma Arizona about 1880's. She was born abt 1860. I don't have any other information other than some of her children's names ( Rufino, Ysabel born 1885,Thomas born 1889 and Luis born 1893)Carmen died shortly after Luis was born. My grandmother said they were Yaqui and Mayo but I don't know on which side. Thanks any info would be appreciated. I just started my research.
