Jose:

I don't know if you had yet found the record of Rafael Maldonado's wedding with Toribia Gonzalez, but it is indexed on IGI and the record should show the parents of the groom and bride. It seems that you already have the parents of the bride.

RAFAEL MALDONADO
Spouse: TORIBIA CURS
Marriage: 11 OCT 1855 San Cosme, Villa De Cos, Zacatecas, Mexico
Batch No.: M605383 Film Number 1094899

You should get to your closest Family History Center and order the film in which the marriage appears.

I also notice that Toribia's family comes from Tepechitlan and El Teul. These are areas that I have researched.
