Arwen was the youngest child of Elrond, lord of the Elvish sanctuary of Rivendell and leader of the High Elves remaining in Middle-earth at the end of the Third Age, and Celebrían, daughter of Galadriel, ruler of the Elvish forest realm of Lothlórien. Her elder brothers were the twins Elladan and Elrohir.
Arwen was also a descendant of High King Turgon of the Ñoldor through her great-grandmother, Idril. Through her mother, she was the granddaughter of the Lady Galadriel and the great-granddaughter of Finarfin.
Aragorn was a descendant of Elros Tar-Minyatur through the line of the Lords of Andúnië to Elendil, High King of Arnor and Gondor. Like all of the kings before him, he was related to Elrond through the House of Elros.
Arwen probably got to know Legolas as her husband's friend and as the leader of the Elven colony in Ithilien. As Mary Tower points out, it is possible that they are distantly related, but it's nowhere stated.
First off, Galadriel was the first cousin of Turgon, who was Elrond's great-grandfather, which made them first cousins thrice removed. Furthermore, Elrond was the great-great-grandson of Galadriel's uncle, Fingolfin.
The Third Age. At the beginning of the Third Age, Elrond married Celebrían, daughter of Galadriel. They had three children: twin sons, Elladan and Elrohir, and a daughter, Arwen.
Legolas does not marry or have any children, based on the appendix of The Lord of the Rings. Regardless of who his mother was, Legolas is the last of his line. When he sails into the West at the beginning of the Fourth Age, he leaves no family members behind.
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. Do you A) nick all the costumes and stay in character the rest of your working life, or B)
It is later mentioned that Tauriel is a talented warrior and was therefore made leader of the Mirkwood border guards. Legolas, the son of Mirkwood's Elven king Thranduil, is indicated to be attracted to her, but as she is a lowly Silvan Elf, she does not believe herself worthy of him.
Aragorn's mother, Gilraen, was one of the Dúnedain - the line of Men descended from Aranath, the last king of Arnor. Her father was Dírhael, and he was good friends with Ardor, the Dúnedain Chieftain and Aragorn's grandfather.
"He was Aragorn son of Arathorn, the nine and thirtieth heir in the right line from Isildur, and yet more like Elendil than any before him." Aragorn was a descendant of Elros Tar-Minyatur. His ancestorArvedui was wedded to Fíriel, who bore their son Aranarth, making Aragorn the last descendant of Anárion as well.
However, he does not possess the ability to live forever, and he cannot choose to be mortal or immortal like Arwen, the half-Elf he loves and eventually claims as his wife. Because Aragorn is mortal and Arwen chose to remain in Gondor and become mortal, their son, Eldarion, is mortal as well, despite his Elven lineage.
We know precisely nothing about Legolas's mother. In the Hobbit movie trilogy, they had some lines that suggest that she was killed by orcs but that is entirely non-canon. We know that Legolas's father Thranduil is a Sindar Elf so we could probably assume his mother is as well.
However, their relationship remains purely platonic in Tolkien's source material. It's true Gandalf is in awe of Galadriel's beauty, but that isn't anything special. Everyone is in awe of Galadriel.
What happened to Arwen's mother in Lord of the Rings?
She was captured and tormented, receiving a poisoned wound. Her sons rescued her and she was physically healed by Elrond, but never fully recovered in mind or spirit, and no longer wished to stay in Middle-earth. She left for the Grey Havens and passed over the Great Sea the following year.
However, a specific scene in The Lord of the Rings has led fans to theorize that Frodo and Legolas didn't talk, not because of time, but because the hobbit didn't know Legolas' name (and was too embarrassed to ask).
In LotR, he had brown eyes and in the hobbit he had blue eyes. Did anyone else notice this? Or was it just me? Apparently Orlando was allergic to the contact lenses in LotR, so he didn't wear them... but he did in The Hobbit.
Originally Answered: Why does Legolas look so different in The Hobbit? They made him look much more angry and old. By the time PJ filmed the Hobbit Orlando Bloom's (Legolas ) body had matured from that of a young man of 22 to a mature man of 30+. He had aged.
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.
Tauriel gave her love to Kili in the movies. In “Laws and Customs of the Eldar”, or LACE, it talks about elves, and that they do not marry unless they truly love one another.
Galadriel was one of the Ñoldor who came to Middle-earth wishing to see the lands and rule a realm of her own. She came with the second host of Elves from Aman with Fingolfin and Finrod. In Doriath, she and Celeborn fell in love and married.
Defeated by the Host of Valinor in the War of Wrath, Morgoth was banished from Middle-earth into the Timeless Void, though it was prophesied that he would one day return.
