Born III 241 - Died IV 121
Arwen Evenstar (or Undómiel) was the daughter of Elrond Peredhil and Celebrían and grand-daughter of Galadriel and Celeborn.
Like all of Elrond's kin she was forced to make a choice between mortality (staying with humans and dying as one) or immortality (passing on to Aman with the rest of the Elves). She chose mortality and married Aragorn becoming queen of the Reunited Kingdom, formed after the defeat of Sauron on 25 March IV 1.
The name "Arwen" means "noble maiden."
