Nahald
From Tolkien Gateway
Nahald 'secret' is the original Hobbit name of Déagol, the Stoor who originally found the One Ring and was murdered by Sméagol (Trahald).
In Déagol's days (mid-25th century Third Age) the hobbits who lived in the Vales of Anduin used language which was related to the Northern tongues of the Men.
