Hello. I am searching the Cornejo line from Jalisco. More specifically, from the areas of San Juan de Los Lagos, Encarnacion de Diaz but it has now led me to Teocaltiche.

Hello. I am searching the Cornejo line from Jalisco. More specifically, from the areas of San Juan de Los Lagos, Encarnacion de Diaz but it has now led me to Teocaltiche. Unfortunately, I am stuck on Blas Ramirez Cornejo (late 1600’s, early 1700s). Does anyone have any leads as to who his parents were?
Thanks in advance!
