Gertrudis Romero de Chaves

I can’t understand the marriage references to Joseph Gonzalez de Hermosillo and Gertrudis Romero. It looks like she is the daughter of Lucas Romero de Chaves and petronila Gonzalez de Hermosillo but the record says she is Gertrudis Romero de Mora or Zamora.

Can someone clear this up for me?

Thank you for your help.
