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.
Amras' father-name in Quenya is Telufinwë, "Last Finwë", for he was the last of Fëanor's sons. His mother name was originally Ambarussa ("top-russet", referring to his hair), the same as his brother Amrod, but Fëanor insisted that the twins ought to have different names and Nerdanel later called him Umbarto, "The Fated". His father, disturbed by it, changed it to Ambarto. Nevertheless both twins called each other Ambarussa.

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.
