Faelivrin was the name that Gwindor bestowed upon Finduilas, the daughter of King Orodreth of Nargothrond, due to his love for her beauty. This name referred to "the gleam of the sun on the pools of Ivrin". Finduilas had loved Gwindor (they had been betrothed before the Nirnaeth Arnoediad) but soon her heart turned to the man that Gwindor had brought into the Elven kingdom, Túrin.

Faelivrin (name)
Daughter of Orodreth who loved Túrin (S/209). The initial element of her name seems to be fîn “hair” (SA/fin), but the meaning of the rest of her name is unclear. This was also the name of the wife of Denethor (LotR/961).
Conceptual Development: When this character first appeared in the Lays of Beleriand from the 1920s, she was briefly named ᴱN. Findóriel, but was soon renamed ᴱN. Finduilas (LB/81), which remained her name thereafter. This name was also briefly used for the characters Arwen (WR/370) and Galadriel (TI/249).
