One modern scholar, Manuel Carriedo Tejedo ("La Version de la "Historia Silense" Sobre la Filiacion de Vermudo II", Tierras de León: Revista de la Diputación Provincial, (1981) 21(44), 38-44), has argued that Ordoño IV was instead son of Galician king Alfonso Fróilaz, a paternity for Ordoño IV also favored by Claudio Sánchez-Albornoz. García Álvarez, "Ordoño IV" refutes this view, as does Emilio Sáez Sánchez (1947), "Sobre la Filiacion de Ordoño IV", Cuadernos de Estudios Gallegos, 2, 363-75).
