good to hear from you so quickly. Estrada is a name that I believe was the married name of his mother Felipa Rosales. It seems like she had my grandfather Pablo Gonzales out of wedlock and then married Felipe Estrada or she was widowed by Sevas Gonzales and then married Felipe Estrada. All this seems like it happened in Pozo Hondo Zacatecas. I say this because I have a baptismal cert of their dtr Maria Luisa baptised in Nieves, Zacatecas in 1884. Do you have Estrada, Losoya or Rosales or Villegas from Zacatecas? I know for a fact my grandfather and Maximiana later moved to San Pedro de las Colonias Coahuila. Anything sound familiar to you?
