[The Squatter of Amon Rûdh]

At the Council of Elrond

But many another name he has since been given by other folk: Forn by the Dwarves, Orald by Northern Men, and other names beside. He is a strange creature, but maybe I should have summoned him to our Council.

Orald is an Old English word, so should represent Rohirric. It's likely that it survives from a now extinct language spoken by the ancestors of the Rohirrim before they came to Calenardhon. It's a tenuous link, but I did say that I put this together in a hurry: the link with Calenardhon came from an on-line source that I didn't fact-check.
