Gelmarr, also known as Gelmarr the Grim, is an ironborn raider.
A Clash of Kings
Gelmarr is part of Theon Greyjoy's crew during the harrying of the Stony Shore and the capture of Winterfell. When Bran and Rickon Stark go missing, Gelmarr is part of the search party. Gelmarr, along with Aggar and Gynir, goes with Theon and Reek to the mill at the Acorn Water, where Gelmarr kills the miller's wife with his longaxe.
After the search party returns to Winterfell with the bodies of two children which Theon claims are the bodies of Bran and Rickon, Gelmarr falls down some steps at night and breaks his neck. Aggar and Gynir are also found dead in the following days. Although he knows Reek was responsible for the murders, Theon condemns Farlen for the deaths and personally executes the kennelmaster.
