Thank you for your kind answer. Yes it sounds familiar!!! Diego is a very common name in my ancestors. Manuel and Manuela are also first names very usually in my family. I did remember the surname Lozano been mentioned several times. My Fierro's made many round business trips to Camargo and Delicias Chihuahua, that are nearby cities to Chihuahua, Jimenez and Torreon. They were always talking about these places. My grandmother was Leonarda Fierro Guillen, with many siblings, his father was Felipe Fierro, seems he was from Italian or Portuguese ancestry. Perhaps Diego was related with Felipe?. My ant Lilia describe Felipe as a Caucasian man, tall, handsome, smart, well built, blond hair and blue eyes. He was the owner of a very well known store in Jimenez Chihuahua, called "La Sorpresa", closed by the time of the Mexican revolution. My grand-ant Pascuala, it's is said had been very familiar and friend of Pancho Villa. She lived until 1965, died at 93 years old. Seems all the Fierros have had very long lives.
Hope these data let us find a common link in our ancestry,
Thank you again Robert
