Sarai is Haran’s daughter. But Abram and Haran are half brothers, same father Terah but different mothers. This will make Sarai as half half niece of Abram. I think incest will only follow on direct blood line of families, halfies or half lings will break the blood line. As I suspect Lot’s daughters are not his real blood daughters but of his wife that she brought into Lot’s house, possible in Sodom & Gomorrah sexual lasciviousness, so Lot’s wife could be cheating on him.
