Llamas mystery

Hello,
I'm trying to trace the maternal line of Juana Llamas Venegas, b ~1730, either in Tepechitlan or Jalpa. There are two family trees that show her father and grandfather being Simon Llamas and Mateo Llamas (familysearch.org/pal:/MM9.3.1/TH-1-18427-23966-36?cc=1874591&wc=12512782), and her mother and grandmother being Ana Banegas (Venegas) and Felipa Banegas (familysearch.org/pal:/MM9.3.1/TH-1-18427-25540-38?cc=1874591&wc=12512782).

Simon Llamas married for the second time in 1738, to Getrudis Banuelos, where it's mentioned that his first wife was Feliciana Getrudis Herrera (familysearch.org/pal:/MM9.3.1/TH-1-15261-32055-49?cc=1410092&wc=6839126). A Pedigree Resource File from FHC convinced me the two family trees identify the same Simon referenced in these weddings: https://familysearch.org/pal:/MM9.2.1/SYVJ-HW3.

Has anyone studying this Llama line come across the Banegas family? I'm guessing that Juana Llamas is the illegitimate child of Simon and Ana, but don't want to rule out other possibilities (such as that FeliciANA Herrera and ANA Banegas) are the same person).

Thanks
Arturo
