Questions Pares and Inquisition Records for Ruiz de Esparza

I have two questions. First, does anybody know if the Pasajeros a Indias information that appears in the Pares search engine is complete? I saw a reference to a person as appearing in the Pasajeros books, but when I looked him up on Pares, he wasn't there.

Second, a friend gave me a list of surnames of people investigated by the Inquisition, and the surname Ruiz de Esparza is there. It occurred to me that the surname is there because of the "prueba" that was done on Lope Ruiz de Esparza in Aguascalientes (the one that mentions Petronila de Moctezuma as his wife's ancestor). Whoever put together that list must have a source for the Ruiz de Esparza surname occurring on it. I think it was prepared by John Schmal and was being circulated in the Genealogia de Mexico group (Google groups). Maybe this can help us track down the Limpieza de Sangre for Lope Ruiz de Esparza.
