I am researching the descendants of Jose Pablo Perez (1812-1892) and Ma. Vicenta Barrera (1814-1876) of Mier, Mexico and San Diego, Texas. If there are any other descendants who would like to exchange information, please contact me. I would be happy to share what I have gathered with anyone interested. Anastacio Perez and Manuel Perez were my third great grandfathers. I have some photos, as well.
