Rían
daughter of Belegund, the nephew of Barahir, she was the wife of Huor (of the Hador) and mother of Tuor (who married Idril the elf). Rían is the grandmother of Eärendil (Elrond's father), which is where part of his Edain (Human) bloodline comes from.

Rían was born around 450 of the First Age. She was gentle of heart and loved neither war or hunting. She loved the trees and the flowers of the wild often sang songs. After the disasterous Dagor Bragollach ("Battle of Sudden Flame" in 455 FA), Rían and her cousin Morwen were refugees along with Emeldir and others of the House of Bëor. Most went to Brethil, but the two cousins, however, continued on and fled to Dor-lómin. It was here, the home of the House of Hador, where she met Huor. They were married only two months when Huor left with his brother Húrin to fight in the Nirnaeth Arnoediad. When she did not hear news of her husband she fled into the wild but was aided by the Grey-elves of Mithrim. There she bore her son Tuor and he was raised by the Elves. Rían learned from the Elves that Huor had died in the Battle so she left Mithrim and went to Haudh-en-Ndengin, the Mound of the Slain, where the bodies of Elves and Men from the War were buried. She laid herself upon it and died of grief.
