I need the opinions of the many experts on this site

There are so many knowledgeable people on this site, I would like to know the best way to validate that the children who were baptized in San Juan are really the siblings of those baptized in San Diego de Alejandría.

Through IGI records, I found the following children of Juan Antonio De Anda, Gertrudis Padilla:

Jose Claro Anda Padilla
residence:Jalisco, Mexico
baptism/christening date:18 Aug 1822
baptism/christening place:
SAN JUAN DE LOS LAGOS,JALISCO,MEXICO

Jose Todosio Anda Padilla
residence:Jalisco, Mexico
baptism/christening date:06 Jun 1824
baptism/christening place:
SAN JUAN DE LOS LAGOS,JALISCO,MEXICO

José Luis De Jesus De Anda
birth:Mentidero residence: San Diego de Alejandría, Jalisco, Mexico
baptism/christening date:27 Aug 1826
baptism/christening place:
La Inmaculada Concepción, San Diego de Alejandría, Jalisco, Mexico

Nicolas De Guadalupe De Anda
birth: Mentidero
residence:San Diego de Alejandría, Jalisco, Mexico
baptism/christening date:16 Dec 1828
baptism/christening place:
La Inmaculada Concepción, San Diego de Alejandría, Jalisco, Mexico

Ma. De La Crus Anda Padilla
residence:Jalisco, Mexico
baptism/christening date:11 May 1831
baptism/christening place:
SAN JUAN DE LOS LAGOS,JALISCO,MEXICO

What are the chances of two Juan Antonio De Anda being married to two Gertrudis Padilla? I know the San Juande los Lagos and San Diego de Alejandría are very close to each other but why would a family not go to the same church for all of their children?
