Amras (Years of the Trees – First Age 1) and his twin brother Amrod were the youngest sons of Fëanor. Through their mother Nerdanel they inherited red hair (probably a dark red), instead of Fëanor's black. He joined his brothers in the Oath of Fëanor, but was accidentally killed in the swan ships of the Teleri when his father ordered them to be burnt at Losgar. In the published Silmarillion and in earlier texts he is said to have lived on to Beleriand and ruled with his twin Amrod over lands west of the Blue Mountains.
Amras' father-name in Quenya was Telufinwë, "Last [of] Finwë", for he was the last of the sons of the House of Finwë. His mother-name was originally Ambarussa ("Top-russet", referring to his hair), the same as his twin Amrod, but Fëanor insisted that the twins ought to have different names and Nerdanel prophetically called him Umbarto, "The Fated" (from umbar = "fate"). His father, disturbed by it, changed it to Ambarto, "Upwards-exalted" (from amba = "upwards, top" and arta = "exalted"). Nevertheless both twins called each other Ambarussa.
The name Amras is the Sindarin version of the short form of Telufinwë, Telvo.
In later notes found in The Peoples of Middle-earth, Tolkien mentions that he wished to change the name to Amros because of linguistic issues. While this occured late in life, and there are no known manuscripts written later that contradict this, its canonicity is in dispute.

Other Versions of the Legendarium
There is no trace of the death of Amras at Losgar in the published Silmarillion, as it was a very late idea by Tolkien, omitted by Christopher Tolkien as he did not at the time see how it could be incorporated into the primary text of The Silmarillion. Where both Amrod and Amras are mentioned in the published text after the landing in Losgar, it should according to Tolkien's later wishes be Amrod alone. The information regarding Amras' naming, especially, comes from The Peoples of Middle-earth.
