I too am searching for Falcon in Texas - mostly from/around San Antonio and the Hill Country of Texas.
Since I posted today about Falcons in Hill Country, Texas, I shall just repeat names here:
Juan Falcon m. Falstina Gonzales Pedro Gonzales Falcon m. Elena Torres Hesbrook
Pedro and Elena had twelve children: Salsatina or "Tina", Guillermo or "Willie", Apollonia, Alcadia, Elena, Charlie, Santos, Alvena, Dorothy, and my great-grandmother: Delfina. If any of these names come up in your research, please feel free to contact me at: Dingyell@webtv.net.
