Hello I am Leonard. I want to say that I hope you are doing well. My grandfather never spoke about our relatives on his side. But if you are related to us there is a book called Los Vidaurris de Cohuilla written by Jose de La Pena. He is my grandfathers sister Ramonas son. You can buy it at borderland bookstore. It traces our family way back. I actually am in the process of moving and have no idea which box has all my family info. When I find it I will let you know.
