Hola Jaime; Other than that I seem to recall a posting here about an 1829 marriage joining Balderrama and Fierro possibly in Satevo, I know nil about Balderrama history in that municipio.I did meet a cousin there in 1971 who joined my family in visiting Luz Corral and showed me about Cd. chihuahua as well. His name is listed in the Chihuahua phone directory on a page sent to me by Carolina Tomkinson Gomez del Barrio, there are Balderramas in her family as well as Hierros. DO check out her site: GOMEZ del BARRIO of LOS ANGELES her search includes Spain. I dont recall Holguin, but do look at the list of surnames on that site. Also i found a couple of Balderramas in ALMADAS Diccionario de Chihuahua in the PERIODICOS section: a Balderrama was redactor of the frst Boletin Oficial of Chih. in 1835. As I recall there are Balderramas listed as well under their surname. They appear to be close cousins to me and I'm sure have intermarried with my family many times over, with Fierros and hierros, that is . Carolina sent me a page of Hierros and del Hierros in that phone directory and I plan to write them, as i dont doubt that there is family there, or at least info. Do you still have my e-mail adress? Antonio P del H.
