does anyone have info. on Cecilia lopez(early landowner in tlaltenango)'s mom

I'm asking this since a few months ago i got my maternal grandma's mtdna results, which were c1c4. I was a bit surpised since i previously thought cecilia was full spanish(the mtdna indicates otherwise). Besides that when i was researching cecilia, i couldn't find much about her mom besides her name. I would like to figure whether it was cecilia's mom or grandma that was full amerindian and whether they were native to tlaltenango or somewhere else.
