Eärendil:

Eärendil was the son of Tuor and Idril, therefore one of the Half-Elven. He was born in the year 541 of the First Age of the Sun, in Gondolin. Eärendil married Elwing and thus united the two lines of the Half-Elven, because Elwing was the granddaughter of Beren and Lúthien. Their sons were Elrond and Elros.

When the surviving sons of Fëanor attacked to recover the Silmaril, Eärendil and Elwing fled into the West, to beg for aid from the Valar for Middle-Earth. It was only due to the Silmaril that they bore that they gained access. Due to the fact that none from Middle-Earth at that time were permitted to enter the Blessed Realm, Eärendil was set in the sky with they Silmaril as a star. During the final wars in Beleriand, he slew Ancalagon the Black. Eärendil sails the skies still, though he is now known as Venus.

Elwing:

The daughter of Dior, who was the son of Beren and Lúthien, Elwing married Eärendil and bore him two sons: Elrond and Elros. She joined Eärendil in his desperate journey into the West. It was due to her having brought him the Silmarill that they finally, successfully made the journey. She now resides on the western coast of Aman, in a tower that the sea-birds flock to.

Elrond:

One of the two sons of Eärendil and Elwing, Elrond was born in the First Age of the Sun. Being one of the Half-elven and permitted to chose which race he would belong to, Elrond chose the Firstborn, the Eldar. Elrond was the Keeper of the strongest of the Elven-rings, Vilya, the Ring of Air, the Ring of Sapphire. In 1697 of the Second Age of the Sun, he founded Rivendell, or in the Elven tongue, Imladris. After the War of the Ring, he sailed into the West with the Ringbearers and the Keepers of the other two Elven Rings in the year 3021 of the Third Age.

Elros:

The second son of Eärendil and Elwing, Elrond's brother, Elros chose to be of the race of Men. He was granted a span of years five times greater than that of most Men. Elros was the first King of Númenor, after the destruction of Beleriand.

Elendil:

The first High King of the Realms in Exile, Elendil and his two sons, Isildur and Anárion, escaped the ruin of Númenor with nine ships. Elendil was slain at the very end of the War of the Last Alliance, by Sauron on the slopes of Oroduin, the Mountain of Fire.

Elanor Gamgee:

The eldest child of Samwise Gamgee and his wife, Rosie, she was born in the first year of the Fourth Age. Called Elanor the Fair, for her beauty, Elanor was named after the flower, that Sam saw in Lothlórien. For a while she was a handmaiden to Queen Arwen. After she married, both Elanor and her husband moved to Undertowers, where they were eventually given charge of the Red Book.

Éowyn:

Born in the year 2995 of the Third Age, Éowyn was the niece of King Théoden. During the War of the Ring, she was left to be the leader of those who were to flee to Dunharrow, during the Battle of Helms Deep. It was just before that battle, when Gandalf, Gimli, Legolas and Aragorn, joined the host of the Eorlingas, led by King Théoden and Éomer, her brother, that she met Aragorn, and she loved him from the first sight. On their return to Dunharrow, en route to the Paths of the Dead, Éowyn begged to be allowed to join the Grey Company for that journey. Aragorn did not accept and Éowyn rode in disguise with the host of the Rohirrim under the name of Dernhelm. It was as a Knight of the Riddermark, that she carried Merry into the Battle of the Pelennor Fields where with his aid, she slew the Lord of the Nazgûl, Witch-King of Angmar. She was healed of the injuries caused to her in that act by Aragorn, and later married Faramir, Prince of Ithilien. She was ever after known as the Lady of the Shield Arm for that arm had been broken by the mace of the Witch-King.

Éomer:

Second Marshal of the Riddermark, Éomer was born in the year 2991 of the Third Age. His father was Éomund, probably also a Marshal. Éomer had one sister, Éowyn. In the year 3018, Éomer encountered the Three Hunters, Aragorn, Legolas and Gimli, while out without Théoden's leave chasing a patrol of Saruman's orcs. He lent them two horses, Hasufel, and Arod, with the request that they return to Edoras, after their quest was completed or proved in vain. Thus it was that Aragorn, Legolas, and Gimli joined the host in the Battle of Helms Deep.

Before King Théoden died on the Pelennor Fields, he named Éomer as the next King of the Rohirrim. Éomer was unhurt throughout the rest of the War of the Ring, as far as the records say. After the crowning of Aragorn, Éomer swore the Oath of Eorl again with Aragorn, and always kept it until his death in the year 63 of the Fourth Age.

Éomund:

Éomund was the husband of Théodwyn, sister to King Théoden. His two children were Éomer and Éowyn. Known for his determination in fighting orcs, he was slain on one of those ventures in the year 3002 of the Third Age. At the time, Éomund had been in charge of the East Marches of Rohan as the Chief Marshall of the Mark. At one point, Aragorn says that he had met Eomund while he was in the service of Rohan. This would likely have been in the three year period between 2957 and 2980 of the third Age.

Eldarion:

The eldest child and only son of Aragorn and Arwen. Eldarion was born at some point during the first century of the Fourth Age of the Sun. He came to rule in the year 120 of the Fourth Age. No date is given for his death.

Eonwë:

One of the few maiar named in the surviving records of the Elder Days and the First Age of the Sun in Middle-Earth, Eonwë was the herald of Manwë. Some of the deeds he was recorded as doing included the following: He carried the Doom of Mando to the departing Noldor, took terms to Sauron after the Chaining of Melkor, and instructed the Edain before their departure for Númenor. After the end of the First Age of the Sun, we don't hear any more about him.

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 139 of the Second 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.

Elladan:

Elladan was the brother of Elrohir and Arwen, and son of Elrond and Celebrian. Born in the year 130 of the Third Age of the Sun, as was Elrohir, there is some suggestion that they may be twins.

He was with the Rangers who followed Aragorn through the Paths of the Dead and was a part of the council who decided to fight on the Dagorlad to keep Sauron busy at the end. He, like his brother had acted as a scout with the Rangers to search out the spies of Sauron and the fate of the Nazgul at the beginning of the War of the Ring.

Nobody is quite certain of his fate, as he chose not to sail into the West with his father and the Bearers of the Three. Did he choose the fate of the Edain, or did he sail later? There is a strong suggestion that he and his brother would not have been able to go later and so they must have chosen as their sister did. Either way, no death date is known.

Elwë:

One of the three leaders of the Elves who visited Aman. Elwë was later known as Thingol.
