According to the databook, the Hyuga were only able to preserve it by keeping marriages within the clan, which is the whole point of it having two houses. Same for the Otsutsuki Clan. IIRC, the databook even says there used to be other clans with the Byakugan, but it disappeared as the Otsutsuki bloodline thinned. well let the time answer that question
