Hello Aaron, I did further research on Diego and Lucrecia. The earliest record I found for them was the baptism of their son Jose Vicente Trevino who was baptized in April 6, 1753 in Montemorelos. I then find that they baptized another child, Maria Ignacia Albina Trevino in Camargo in December 25, 1767. I can’t find a record for Diego and Lucrecia that mentions their parents. As for the mtDNA it is a probability that she may descend from Maria de la Cerda but don’t rule out that she may not.
