I've recently discovered that the marriage record of Maria de la
Encarnacion Quesada and Julio Joseph Robalcaba, dated Feb 14, 1770 in
Nochistlan, incorrectly identifies her parents as Manuel Aguirre and
Gertudis Ximenes. The dispensation (1770, 1773 FHL Source Film 168044 -
Mexico Genealogy, Images 92-97, (thank you Claudia et al)) identifies the
parents as Joseph Manuel Quesada and Maria Magdalina Lopez( Lizaldi).
I hope this is helpful.
