What was the name of Abraham's nephew who was rescued by angels from Sodom just before it was destroyed by God

In Genesis 18, God sends two angels, appearing as men, to Abraham in the plains of Mamre. After receiving the hospitality of Abraham and Sarah, his wife, God reveals to Abraham that he will investigate Sodom and Gomorrah, because their cry is great, "and because their sin is very grievous." (vs. 20-21) In response, Abraham reverently inquires of God if he would spare the city if 50 righteous people were found in it, then 45, then 30, then 20, or even ten, with God affirming he would not destroy it after each request, for the sake of the righteous yet dwelling therein. The two angels of God proceed to Sodom and are met by Abraham's righteous nephew Lot, who constrains the angels to lodge with him, and they eat with his family.

When they had not yet retired, and the men of the city, the men of Sodom, surrounded the house, both young and old from every end of the city. And they called to Lot and said to him, "Where are the men who came to you tonight? Bring them out to us, and let us know them."

In response, Lot refuses to give his guests to the inhabitants of Sodom, and instead offers them his two unmarried daughters, "who have not known man", to do with as they please. However, they refuse this offer, and threaten to do worse to Lot than they would have done to his guests, and press sore upon him. Lot's angelic guests rescue him, and strike the men with blindness. They then command Lot to gather his family and leave, revealing that they were sent to destroy Sodom and Gomorrah. As they make their escape the angels command Lot and his family not to look back under any circumstance. However as Sodom and Gomorrah were destroyed with fire and brimstone by God, Lot's wife looks back longingly at the city, and becomes a pillar of salt.
