Villalpando Families from Asientos

I am working on the descendants of Tomas de Villalpando who was from Leon, Guanajuato, and his wife Maria Velez.

At least one of their sons, Tomas, moved to Aguascalientes and left many descendants in the towns of Aguascalientes and Asientos.

The are three marriages of Villalpandos that I am having trouble connecting:

Marcos de Villalpando, from Leon, married Micaela Diaz de Leon, in Asientos 20 Feb 1713 (Asientos marriages, 1705-17, image 37) [the Tomas de Villalpando who moved to Agascalientes had a brother named Marcos who married in Leon; there is no indication in this record that Marcos was a widower.]

Nicolas de Luebana and Juana de Villalpando, married 29 Dec 1713, in Asientos (Asientos marriages 1705-17, image 31)

Tomas de Villalpando and Maria Gentil Gallardo married 24 Mar 1711, in Asientos (Asientos marriages 1705-17, image 29)

Does anyone have information on the parents of these Villalpandos?
