The Villagrana's from Zacatecas

Hi, I had a question...Is it possible for Mexican couples such as in the 1800's, to have gotten married as early as 10 and 13 yrs old? If so, I think I've finally stumbled onto something...

As you know, I have been trying to research my great grandfather Felix Villagrana and related Villagran/Villagrana ancestors from Zacatecas, Mexico. I think I may have found the people I was looking for! So far, everything I've found with this family has matched my suspicions and clues I had from family...
