Islas and Toledo de Nochistlan

I have an M Islas Gonzalez (given name may be Maria Luisa, there is an
inkblot over most of that part), married to Pedro Antonio Toledo y
Balenzuela, listed as the parents of Luis Toledo, who married Petrona de
Jesus Garcia in Nochistlan on 8 Feb, 1750. Luis Toledo is suppose to be
from the area, but I have not found any other Toledos in that period there,
nor any Islas Gonzalez. I've noted both Islas and Toledos mentioned
recently. Does anyone have anything? Thanks for sharing if you do!--Raquel
