Duinhir was lord of the Blackroot Vale at the time of the War of the Ring and with his sons fought in the Battle of the Pelennor Fields. The only descriptive information known about Duinhir was that he was "tall".
On 10 March, T.A. 3019, Duinhir led a contingent of five hundred bowmen as well as his two sons, Duilin and Derufin, into Minas Tirith to fight in the upcoming battle. Sadly, Lord Duinhir lost both of his sons in the fray (on 15 March) when they were trampled by mûmakil while attempting to shoot out the monsters' eyes.
Duinhir means "River-lord" in Sindarin.
