The Spanish Archives of New Mexico may have records on your ancestors since many of them where Spanish explorers and even led explorations into what is now New Mexico.
Many of them also stayed there and helped colonize it but many of their children ended back in what is now Mexico.
If you have traced your ancestors to New Mexico or as it used to be called Nuevo Mexico, then you might want to look into the two PDF eBooks that I found last month.
The eBooks are The Spanish Archives of New Mexico Volume 1 and Volume 2.
