Juan de Salas and Gertrudis de Avila - Jerez

Hello,

I'm looking for any information regarding Juan de Salas and Getrudis de Avila. The only thing that I know is that the mother of Gertrudis de Avila was Cecilia de Arzola. I don't know anything about Juan de Salas.
Any information would be greatly appreciated

saludos
