Glad you found Joseph Dionicio's parents.  I thought it would be one 
of these two:

JOSEPH DIONICIO RAYGOSA MOJARRO
Gender: Male Christening: 06 DEC 1731 Tlaltenango De Sanchez Roman, 
Zacatecas, Mexico

JOSEPH DIONICIO RAIGOSA MARTINES
Gender: Male Christening: 05 MAR 1741 Tlaltenango De Sanchez Roman, 
Zacatecas, Mexico

I wonder if the Rosalia could be this one instead:

MA. DE LA LUZ ROSALIA CASTANEDA LOPES
Gender: Female Christening: 11 APR 1745 Tlaltenango De Sanchez Roman, 
Zacatecas, Mexico 

The other one seems too young to be married in 1764, though I do 
realize sometimes people did get married that young...

I'll send you a list of the descendants that I have tomorrow.
