we are searching for possible relitives from the Magdalena, Sonora area. our grandmother was from that area or nearby. her name was Josefa "Parada"(before marriage), her mother was surnamed "Corona". all we know is that they where of "Yaqui/Mayo" stock. near turn of last century(1800-1900) some family members moved to Arizona. we would also like any information about the Yaqui/Mayo living in that area during these time and their conditions.
