Did Luis de Lomelin have two children named Francisco and Juan Lomelin?

Hello Primos and Primas,

As part of my Valladolid Dispensas work, I ran across this matrimonial dispensation from Tinguindin, Michoacan:

Juan Manuel de Villasenor y Juana de Balbuena (Tinguindin - 1717)

In it, we find that Juan Manuel de Villasenor (vecino de Tlazazalca) was the son of Pedro de Villasenor and Maria de Jaso. Juana de Balbuena (vecina de Tinguindin) was the daughter of Fernando de Balbuena and Leonor de Santa Cruz y Villasenor.

Interestingly, the witnesses call out that there are two parentescos between the novios. The first one is the one I need help understanding and connecting the dots on:

Tronco del primer parentesco: Luis de Lomelin

1. Francisco de Lomelin // Juan de Lomelin
2. Maria de Lomelin // Maria de Lomelin
3. Pedro de Villasenor // Fernando de Balbuena
4. Juan Manuel de Villasenor // Juana de Balbuena

I looked around and couldn't seem to find any traces of a Luis de Lomelin son named Francisco nor that of a son named Juan... What I find interesting is that the third witness refers to the Maria de Lomelins (daughters of Francisco and Juan) as Cuebas and NOT Lomelin like the first two witnesses... That got me thinking... Is it possible that the first two witnesses were not old enough to remember/know that the Marias de Lomelins were NOT daughters of two Lomelin brothers but that they were daughters of two Cuebas brothers? Before I go there, I'd like to like to hear from the group if there were any known Lomelin brothers named Francisco and Juan Lomelin, sons of Luis Lomelin.

Thank You,

Daniel Serna Valencia
