Post-flood lineage: Shem ... Serug > Nahor > Terah > Abram (Abraham), Nahor and Haran
Two different Semites named Nahor both exist in Abraham's lineage - his brother took the name of his grand-father of the same name.
According to Genesis 11:25, Abraham's grand-father lived 119 yrs. He is also mentioned in 1 Chronicles 1:26.
In contrast, Abraham's brother Nahor merely is mentioned as husband of Milcah in Genesis 11:29 and the grandfather of Rebekah who Isaac married.
Genesis 11:22-29:
22. When Serug had lived 30 years, he became the father of Nahor.
23. And after he became the father of Nahor, Serug lived 200 years and had other sons and daughters.
24. When Nahor had lived 29 years, he became the father of Terah.
25. And after he became the father of Terah, Nahor lived 119 years and had other sons and daughters.
26. After Terah had lived 70 years, he became the father of Abram, Nahor and Haran.
27. This is the account of Terah. Terah became the father of Abram, Nahor and Haran. And Haran became the father of Lot.
28. While his father Terah was still alive, Haran died in Ur of the Chaldeans, in the land of his birth.
29. Abram and Nahor both married. The name of Abram's wife was Sarai, and the name of Nahor's wife was Milcah; she was the daughter of Haran, the father of both Milcah and Iscah.
Abraham's brother had sons through Milcah as stated in Genesis 22:20-23:
20. Some time later Abraham was told, "Milcah is also a mother; she has borne sons to your brother Nahor:
21. Uz the firstborn, Buz his brother, Kemuel (the father of Aram),
22. Kesed, Hazo, Pildash, Jidlaph and Bethuel."
23. Bethuel became the father of Rebekah. Milcah bore these eight sons to Abraham's brother Nahor.
24. His concubine, whose name was Reumah, also had sons: Tebah, Gaham, Tahash and Maacah.
In Genesis 24:10, Abraham sent his "chief servant" with Isaac to look for a wife with the primary stipulation that she wasn't from Canaanite roots.
It named a town named Nahor which could have been named after either of the 2 men already mentioned. King James calls it a city, so it was apparently well established.
This is where Isaac met Rebekah who he would later marry.
10. Then the servant took ten of his master's camels and left, taking with him all kinds of good things from his master. He set out for Aram Naharaim and made his way to the town of Nahor.
11. He had the camels kneel down near the well outside the town; it was toward evening, the time the women go out to draw water.
12. Then he prayed, "O LORD, God of my master Abraham, give me success today, and show kindness to my master Abraham.
13. See, I am standing beside this spring, and the daughters of the townspeople are coming out to draw water.
14. May it be that when I say to a girl, `Please let down your jar that I may have a drink,' and she says, `Drink, and I'll water your camels too'--let her be the one you have chosen for your servant Isaac. By this I will know that you have shown kindness to my master."
15. Before he had finished praying, Rebekah came out with her jar on her shoulder. She was the daughter of Bethuel son of Milcah, who was the wife of Abraham's brother Nahor.
Genesis 24 verses 24 and 47 reiterate that she was the daughter of Bethuel, Nahor's son.
Jacob, Issac's son, during his own journey to find a wife among their own people, inquired about Laban, Nahor's grandson in Genesis 29:5 before he met Rachel, his daughter. Luke 3:34 confirms that Jacob was in Nahor's lineage through Abraham and ultimately also a part of Jesus' lineage.
In Joshua 24:2, it said: "...Long ago your forefathers, including Terah the father of Abraham and Nahor, lived beyond the River and worshiped other gods" yet in Genesis 31:53, Nahor worshipped God just as Abraham did.
