what a great story to find! hello my name is priscilla hinostroza. i am 26 years old and i live in california. I also have a Great-Grandfather from Camargo,Ch named Esteban Fierro. He married my great-grandmother Maria Vega, whom he had 5 children with the last being my grandmother Isela Fierro Vega. He is supposedly the brother of Rodolfo Fierro. So I just feel like are two stories and people might have to do with each other.
