In this Matrimonio de Ypina (Ypinas have a history with several Coronados names unknown) he reveals to son of Don Antonio de Campa y Cos that he had an affair with a relative of his that he did not find out until later it was his relative and had to reveal this to him. The Son of Campa y Cos states that his father had a natural child named Juana whose mother was a Mulata de Fresnillo. Juana de la Campa had a child named Gertrudis who was with Ypino and is therefore cousin to his pretensa.
