Looking for information about María Crestina Macías Valadés (Española), usually spelled Masias Balades, AKA Ximénes AKA Péres.

She was probably born in Aguascalientes about, or before, 1733 (guess based upon her children's dates of birth). She married José Santiago Rodríguez sometime before 1748.

She was mostly referred to as "Crestina Macias" but her surname was given in various records as "Masias Balades," "Peres" and "Ximénes." 

I cannot find a baptism record for her, so I've been looking through the Macías Valadés family to find marriages with anyone with the surnames Jiménez or Pérez without much luck. 

Any suggestions or info would be appreciated.

Thanks,

Travis
