The second son of Finwë and half-brother to Fëanor. After Fëanor's death, his eldest son Maedhros should have become High King of the Noldor, but Maedhros repented his deeds at the Kinslaying and refused the title, which thus passed to Fingolfin.

He ruled the lands to the northwest of Beleriand with his sons Fingon and Turgon, and dwelt behind the mountain fences of Hithlum during the long Siege of Angband.

When Morgoth broke the Siege in the Dagor Bragollach, Fingolfin was prevented from sending immediate help to the other princes of the Noldor by the ferocity of the onslaught, but when heard of the extent of their defeat, he rode in anger to the doors of Angband and demanded single combat with Morgoth. There they fought a mighty battle, but though Fingolfin wounded the Dark Lord, he could not prevail, and was finally crushed by Morgoth. His body was saved, though, by Thorondor, who bore it to a peak in the Encircling Mountains. Turgon came there and built a cairn over his father's remains.

The youngest of Finwë's three sons; when his half-brother Fëanor led the host of the Noldor back to Middle-earth, Finarfin chose to remain in Valinor, and became King of those Noldor who remained also. His five children, Finrod, Orodreth, Angrod, Aegnor and Galadriel, all followed Fëanor into the east.

The son of Finarfin and younger brother to Finrod Felagund; he ruled in Nargothrond after Finrod was lost in the dungeons of Tol-in-Gaurhoth.

I think you all know who Galadriel is... I'll post her bio later...

Eldest of Fingolfin's children, who inherited the Kingship of the Noldor after his father was slain by Morgoth. He is famed for rescuing Maedhros from Thangorodrim, and thereby healing the rift between the Houses of the Noldor. As High King, he commanded the assault upon Morgoth that became known as the Nirnaeth Arnoediad, the Unnumbered Tears, and in that assault he was himself slain by Gothmog, Lord of Balrogs. A fact that is not written in the Quenta Silmarillion: Gothmog slayed him while they played Bloodbowl. He was hiding under the skin of a human blitzer. Just in the last turn of the final game, he slayed Fingon to death.

The son of Finarfin and elder brother of Galadriel; he held Dorthonion with his brother Aegnor, and was lost in the Dagor Bragollach.

The son of Finarfin and elder brother of Galadriel, lost in the Dagor Bragollach.

The second son of Fingolfin and younger brother to Fingon, Turgon ruled in Nevrast until Ulmo led him to the hidden valley of Tumladen, where he founded and ruled the city of Gondolin.

And Aredhel the 2nd. She is a clone of Aredhel the first... maybe Melkor made her to confuse the team?

The son of Eöl and Aredhel Ar-Feiniel; he escaped his father's halls in Nan Elmoth with his mother, and came with her to Gondolin. Many years later, he was captured by the spies of Morgoth and betrayed the city.
