サンチョ2世
His genealogy is obscure, but he was probably a son of Sancho II Sánchez. There is much confusion among the sources about the identity of Sancho Mitarra. Some give that sobriquet to Sancho II, while some give it to Sancho III. Some call the latter Mitarra Sancho and call him a son of the former. It seems likely that these two Sanchos are related. Genealogies of a "phantasmagorical" character assign to him a Castilian parentage.
