Hard to say. We never saw Hinata and Hanabi mother's in the manga and I don't recall seeing Neji's mother either. So there is no proof they were Hyuga before marriage (nor there is proof they were not). That and if they are large clan I think they could have non-incest internal marriages. With Uchihas we at least know Itachi was dating someone from his clan.
