My Grandma was a Yescas. I am not sure what her true name was but have found through many searches Elena, Elana, Alina, Helena and Helen. She was born in Cananea Mexico. In the immigration records it show a Santos Yescas as her father but for all I know that could be her brother. Elena Yescas married my grandfather Francisco Corona and immigrated to Arizona in 1924. I am told that through my Grandma we have Yaqui roots but have been unsuccessful in finding any information to prove this. I remember when I was very small we lived on a reservation in Arizona but do not know which one. We moved to Calif when I was 5. All of my relatives that would have any info have all passed on so I have been at a standstill.
