Manny, this is a great find which corroborates the information in the post by Guillermo don Teresa Tovar regarding the 'testamento' of Esteban de Pastrana: "Tengo localizado el testamento de Esteban de Pastrana, vecino de Guadalajara, casado con Catalina Ortíz, y deja como a herederos a sus hijos: Pedro y Juana de Anda, Luisa y María Ortíz. Dice en dicho testamento, fechado en Guadalajara en 10 de junio de 1635, que tiene tratado con Esteban de Anda, tío de su mujer, el pleito por la herencia sobre del capitán Pedro de Anda, padre de su esposa, por ser hermano del dicho Esteban."
Other sons of Esteban de Pastrana and Catalina Ortiz de Anda are: Esteban, baptized on 24 June 1622, and Luis, baptized 28 June 1635, both were baptized in Guadalajara.
The other daughters, Petrona and Juana, named in the document of the 'compañía' between brothers Pedro and Esteban, are new to me. Hopefully, research on these sisters will yield some new insight on Pedro de Anda.
I have Isabel Ortiz as daughter of Pedro de Anda based on her marriage to Pedro Gómez in Lagos: En dieciocho de junio de 1613 casé y velé a Pedro Gomez, hijo de Diego Gomez y a Ysabel Hortiz, hija de Pedro de Anda, fueron sus padrinos Juan de Burgos y Leonor de Bustos. Presumably both the bride and groom were considered 'españoles' since the record was noted with an 'e' in the margen. The fact that Isabel is not named in the document that you shared, which predates her marriage record, is interesting and merits additional research for documents that confirm Isabel as the daughter of the same Pedro de Anda, brother of Esteban de Anda.
I also have have Pedro Ortiz de Anda, who married Ana Ramírez, as a son of Pedro de Anda. This is supported by the baptism record for José Medel cited by Travis. The scribe naming of Ana Ramírez as 'sobrina' of Esteban de Anda is either an error or perhaps akin to the convention used during that period in time where familial ties were extended to the husband or wife of a relative. Such as when a brother-in-law/sister-in-law would be named as 'hermano' / 'hermana'.
Saludos,
