Hi Deedra (and others):

I believe I have solved out little mystery. Juan Garcia de Alba and Juan Francisco García de Alba are not the same person. They are brothers.

I finally found Juan García de Alba's death record in Autlan: He died 22 May 1779 in Autlan, and Rosa de la Cueva survived him. Here is the link:

Since your earlier message indicated correctly that Francisco died 13 Feb 1773 in Ejutla they cannot be the same person.

So, to prove they are brothers, their respective marriages prove them to be sons of Manuel García de Alba and Nicolasa de Santana.

I know you have these (since you pointed them out to me), but just so all the info is in one place:

Juan García de Alba married Rosa de la Cueva 14 Apr 1738 in Tecolotlán.

And Juan Francisco García de Alba married María Gertrudis Rosales on 19 Feb 1746 in Ejutla.

It is so satisfying when we can figure these things out!

Cheers!
