Question: What by birth is the woman who was to get married to Prince Charles known by?
Sentence (from "Juan de Mendoza, Marquis de la Hinojosa"): Although it is claimed his father was 5th Count of Castrogeriz, it seems under careful inspections that he rather came from a family of landed nobility squires, his father, reported as Antonio Gómez Manrique de Mendoza y Sandoval, being the 6th Sieur of Castrojeriz, and 4th Sieur of Villazopeque, who married first to a certain Isabel de Velasco y nríquez de Ribera, also, apparently, from a rather modest branch of rural proprietors albeit assuming some sort connections with this powerful de Velasco ducal family, (Dukes of Frías).
Relevant evidence: No
