Hi Dan I don't have much on Maria Bernadina Valdez. She was the wife of Jose German Aguilar. I found German and Bernadina listed as the maternal grandparents in the christening documents for the children of their daughter Isabel. Isabel was the wife of Luis Santana. The Santana/Aguilar children were born in Saucillo Aguasc. and baptized in Ojocaliente Zacatecas. Bernadinas son Jose Dionicio baptized 1838 Aguasc.his godparents were Epitana Valdez and Juan Lopez.They came from Satero or Salero???aguasc.
I noticed that you are researching ROMO from Aguascalientes. I am searching for the Santanas. Romo, Aguilar, Valdez, Acosta Valadez, are all part of the Santana family line. Maria Bernadinas son in law Luis Santana is the son of Ramon Santana and Salome Acosta (my direct ancestor)his second wife was Maria Romo. His first wife Salome was the daughter of Bicente Acosta and Manuela Valadez. His second wife Maria was the daughter of Eugenio de Vivar Romo and Guadalupe Martinez. they came from the town Punta. If there is a connection please let me know. Thanks Erna.
