Angie, Carol and Rosalinda:

I am researching the same surnames from Zacatecaz.  I have some 
direct line ancestors that might tie in to yours somehow.  One 
couple:  Manuel Castañeda married to Maria Antonia de la Torre on 16 
Nov 1738 in Tlaltenango de Sánchez Román.  Manuel was the son of 
Pedro Castañeda and María Ulloa. I also have Pedro Castañeda (son of 
Manuel) married to María Gertrudis Luna on 13 Jul 1765 in 
Tepechitlán, Zacatecaz.  I have documented 9 children from the 
marriage of Manuel Castañeda and Maria Antonia de la Torre.  Let me 
know if any of these names tie into one of your lines.
