Don Sebastian de el Aguila and Dona Maria Teresa Lopez de Nava

Hi

I am looking for the parents of Sebastian de el Aguila, married to Dona Maria Teresa Lopez de Nava.

They are named as parents of Don Diego Xavier de el Aguila in his marriage to Anna Maria Valdes 09 Dec 1778.

I have searched high and low for Aguilas in Family Search. There are several Sebastians and one with potential. However, I need Sebastians marriage record to be sure....

Next step is going through images page by page, unless someone already has this information.....and is willing to share!

Regards,
Denise
