My grandfather also had son there I don't know his name but I will contact my sister to get his name. I don't know if he is still living too but my grandfather name was Ignacho Marquez he die around in 1951. my mother name is Melquiades Marques, she has past away already. my family is trying to find out if there are any family left there beside my grandfather son or step-son. thanks
