It is also very likely that the current Ishgardian high houses were already Elezen noble houses before the founding of Ishgard. From a technical stand point, elezen nobility would trace back to their original entrance into Eorzea from the North. This would have most if not all Elezen noble line tracing their history back before there was even a Duskwight/Wildwood split. Houses rise, houses fall, and each of them reinvents their history as the split puts Duskwight and Wildwood at each other's throats following the fall of Gelmorra.
Technically, a house could not claim to have always been Duskwight, but that is probably not going to stop them from doing so. There is that, and what is behind me spoiler tag to consider.
