Elfhelm Son of Eldor (2845-3019)
Elfhelm was a noble man in the king's court, with the title of Marshal. He also led a company under Theoden to Gondor. It was the company that Eowyn, under the guise of Dernhelm, and Merry, were in.
He led the company on the right against the war machines and drove the enemy into the fire pits. He survived the battle and was left in charge of 3000 Rohirrm while the Company of the West rode to the Black Gate. He guarded the pass from Anorien and prevented invaders from attacking eastern Rohan. After the war, he was granted the position of Marshal of the East-Mark by King Eomer.
