The Spanish wikipedia page (https://es.wikipedia.org/wiki/Juan_Alonso_Pimentel_de_Herrera) for Juan Alonso includes "y Quinones" in his last name, but I believe this is incorrect. His mother is an "Enriquez y Tellez-Giron" whereas his first wife is the Quinones. I believe he should just be "Juan Alonso Pimentel de Herrera."
