Elrohir:

Elrohir was one of the three children of Elrond and his wife Celebrian. The others were his brother Elladan and his sister Arwen. He was born in the year 130 of the Third Age of the Sun. He seems to have acted as one of the Rangers of the North, at least during the War of the Ring. We hear of Elrohir and his brother scouting to find out the fates of the Nazgul, and later he traveled south with the Rangers to join Aragorn, and journeyed with him through the Paths of the Dead.

Elrohir did not go into the West with his father and the bearers of the Three. We do not know if he was able to do so later, or if by staying, he chose the fate of Men.
