Yet, since Tolkien does give family trees for other important Elves in the book, such as Galadriel and Elrond, it's clear that Galadriel is not Legolas's mother. (Besides, she is one of the Noldor, not a Silvan or Sindar Elf.)
No. Legolas was not related to Galadriel at all. Except as they were both elves. Legolas was from the el who had never left Middle-earth to go to Aman Valinor.
Celeborn and Galadriel have two children together: a daughter, Celebrían, and a son, Amroth.
Now, as far as I can remember, Tolkien doesn't say “Legolas does not have children.” But Legolas is never mentioned as being a father, and there aren't any mentions in any genealogy charts of Legolas having descendants.
Legolas was the son of Thranduil, King of the Woodland Realm of Northern Mirkwood, who appeared as "the Elvenking" in The Hobbit. Thranduil, one of the Sindar or "Grey Elves", ruled over the Silvan Elves or "Wood-elves" of Mirkwood.
Legolas is the son of Thranduil, King of Mirkwood, and the grandson of Oropher, founder of the Woodland Realm.
The actor is suffering from Legolas Syndrome — where you accidentally get cast into a role that suits you far more than your real-life looks, leaving you with a tricky predicament after the wrap party.
Legolas never marries. The closest he gets is spending the rest of his life, as far as we know, with Gimli; they travel around Middle Earth for decades together, and eventually Gimli is given special dispensation to travel to the Undying Lands with his "friend" Legolas—the only dwarf ever to do so.
They are both elvish nobles, as Legolas is the son of King Thranduil and Arwen is the daughter of Elrond. They are both well-educated and would have known each other as the community of elves is quite small. It's likely they would have been at least friendly with one another.
His prowess with a bow was unmatched among the Fellowship and, as J.R.R. Tolkien stated himself, Legolas was “endowed with the tremendous vitality of Elvish bodies,” as well as an inability to feel terrible hurts, which made it easy for him to travel long distances over rough terrain in only light shoes.
In The Silmarillion, Galadriel and Celeborn meet in the First Age of Middle-earth, in the elven realm of Doriath. They marry and have children, including their daughter Celebrían, who goes on to marry Elrond and give birth to Arwen.
She appears in the novel The Lord of the Rings. Arwen is one of the half-elven who lived during the Third Age; her father was Elrond half-elven, lord of the Elvish sanctuary of Rivendell, while her mother was the Elf Celebrian, daughter of the Elf-queen Galadriel, ruler of Lothlórien.
There, Celeborn and Galadriel met, fell in love, and were soon wedded. Galadriel remained in Doriath with Celeborn after Finrod went to the Caverns of Narog to establish the stronghold of Nargothrond.
“Getting to meet him meant a lot of different things at the same time, because I've been a huge fan since childhood." What people may not realise is that, according to Córdova, Arondir is an ancestor of Legolas.
The elves in the woods were the elves of Lothlorien, ruled by Celeborn and Galadriel (also known as the Lady of the Wood). Legolas on the other hand is a prince of Mirkwood, a completely different forest realm. So it's not that surprising that Legolas doesn't know anyone there.
The Elven Queen of Mirkwood, or Thranduil's wife, was a female Elf married to King Thranduil, therefore being the Queen of Greenwood as well as the mother of Legolas Greenleaf.
Technically, Arwen is Aragorn's aunt, but it's not as weird as it sounds (at least within the context of Middle Earth). The romance and marriage of Arwen and Aragorn are unique in a variety of ways.
He Abandoned Romance For Friendship
Loving Tauriel was a particularly harrowing event for Legolas. So much so, in fact, that he never shows any interest in romance ever again. He never even talks about romance in The Lord of The Rings trilogy.
That said, the people behind the “official movie guide” for The Lord of the Rings list Legolas as being born in the year 87 of the Third Age of Middle-earth, which makes him some 2,931 years old around the time of the War of the Ring, which happened over 3,000 years into the Third Age of Middle-earth.
“You gave me a very special bow, and I look after it.” In related news, sources reveal that I “had such a crush” on Aragorn, son of Arathorn, called Elessar, the Elfstone, Dúnadan, the heir of Isildur Elendil's son of Gondor.
So when she allows this incredible rarity to Gimli, she essentially gives him the three hairs that Feanor demanded of her, because she has looked into his soul and found that he has a good heart and that he desires them for nothing more than to treasure the beautiful days he spent in her lands.
Gimli, Lord of the Glittering Caves
He becomes the Lord of the Glittering Caves, and prospers there for many years, doing great works for the Kings of Gondor and Rohan. He never takes a wife and has no children.
Frodo is portrayed as a reserved and introspective character, while Legolas is more outgoing and extroverted. It's possible that they simply don't have much in common and don't feel the need to engage in conversation with each other. The hobbit didn't talk much with Gimli or Boromir either.
Legolas and Gimli's relationship is strong in The Lord of the Rings, even though it wasn't explicitly romantic in Tolkien's source material. The members of the Fellowship in The Lord of the Rings forge an unbreakable bond while on their mission to destroy the One Ring.
They have a deeply spiritual side that they recognize and listen to, so Legolas could feel that Aragorn was the right person for the right time. Also, there developed a bond of friendship from the long journey they had been on, joined by fear, and loss and HOPE.
