Abraham's family tree

Going by Genisis, when Abraham was in Egypt (and again when in Canaan) he was worried that his wife was so hot that someone would kill him and take her for his own. She was about 66 at the time, but I'm guessing like a really young 66. So he came up with a plan: "When we go through this foreign land, I'm gonna tell everybody that you're my sister, not my wife."

Seems a little wacky? Guess what... she really was his sister. Well, his half sister. They shared a dad (Terah) but not a mom. Oooo, then this gets messy.

24 years later, Abe finally gets that girl preggers. She was a really young 90. Their son/nephew was named Isaac. Isaac went on to marry Rebecca. She was his first cousin once removed, the daughter of Abraham's nephew Bethuel (son of Abraham's kid brother Nahor and his wife Milcah, the daughter of Abraham's other kid brother, Haran).

Haran's son was Lot, whose wife (either "Ado" or "Edith" by tradition, but unnamed in the Bible) was turned into a pillar of salt because she looked backward when her hometown went BANG. So Lot has to canoodle with his daughters in order to father the nations of Moab and Ammon.

Meanwhile, Issac and his triple-cousin Rebecca have a son named Jacob. They arrange to have him marry Rachel, the granddaughter of Betheul.

Eew.
