Your dad is my mom's cousin, her name is Estela Pena Elizondo and she is the daughter of Consuelo Elizondo Davila, my grandma "Chelo" as we call her is the sister of your grandma.
It was nice to find relatives her and that I can contact them. I am now living in Canada but my parents are living in Juarez, Chihuahua, is just in the border with El Paso, TX.
Hope we can get in touch.
