Gaton currently has four duplicates for his spouse and one of his daughters, Ermesinda, also has a duplicate.
From what I can gather, there is no concensus for Gaton's parentage; some believe he was the brother of Ordoño, king of Asturias, and some don't.
I understand that if he was the son of Ramiro, his LNAB should probably be Asturias, and if he was not, Bierzo would (probably) be better. If we follow our current standards, that would extend to his descendants.
On the other hand, if we use the patronymics as LNABs (which is against our standards, but would make this set more recognizable), we do not have this problems.
Help much appreciated :)
