Hi Cuz!
I am also a Coz. My Grandmother, Conception "Chona" Coz Robles, was your grandmothers sister. I am going to invite you to the Coz website, you will be amazed. There are alot of pictures and family tree information. There are some other Coz's in San Diego. We had a family reunion in Yuma and it was great! talk to you later.
