Théoden is a character in J.R.R. Tolkien's Lord of the Rings. He was the king of Rohan, who was controlled by his chief advisor, Grima a.k.a. Wormtongue. When Gandalf came to Rohan, he revealed Wormtongue for what he was, and Théoden regained his senses. He then fought in the Battle of the Pelennor Fields, where he routed the Harad calvary. He was later mortally wounded by one of the Nazgûl.
Théodred is the son of Théoden and Elfhild. He was killed in the First Battle of the Fords of Isen.
Both versions of this Tolkien name would be a great choice for parents looking for a fresh take on Theodore. In 2011, 10 boys were given the name Theoden.
