Familias Frausto y Lara, 1750-1825 Calvillo, Ags.; Hzda. de La Luz, Jaltiches, Ags.

Gabriel Serna b. abt 1750 ,higo de Florentino Serna y Antonia Ruis.
I have been searching among other things, for the Origin of Gabriel Serna & Catarina Frausto. In births she is called Catarina Frausto.
They had 5 children
Narciso b. abt 1800 m.to Sirica Duran y Clara Ortiz
Norberto b.abt 1805 m. to Ramona Cervantes
Ma. Guadalupe b.abt. 1806 m. to Honorato Esparza
Macedonio b.abt 1814 m. to Edwarda Macias
Ydelfonso b.abt 1820 m. to Nicodimes Duran.

Facts i have found..
1. In the Marriage of Ydelfonso she is called Catarina de Lara.
2. In the Confirmation of Ma. Guadalupe she is Catarina Lara.
3. In the Baptism of Macedonio the Godparents are listed as Esteban Frausto y Getrudis Lara.

Since they are named as Godparents to her child and she has been named Frausto and Lara; I am hoping to find that this Esteban Frausto & Getrudis Lara are her parents. Any information you have would be appreciated.
