Notes:

Birth:
I am doubtful about her name. It is known only from the marriage record of her son Jose Leonicio in 1815 at Monclova with Maria Francisca Valdez -- the same name as his mother if the record is correct. So I suspect the record is not correct.

Melchor married Maria Josefa Calderon. Maria was born between 1760 and 1770. [Group Sheet] [Family Chart]
