Njal has a son called Grim, which looks promising. There is actually a Rider of Rohan named Grimbold who would fit, but isn't an it and is the wrong way round. (The fourth son in the saga is Hauskeld; I'm not sure which is the foster-son.)

Linger ...I mean, it almost makes "Glend" again.
If I'm misunderstanding the clue, the river
GREYLIN would fit (Y is known as "Greek I" in French, which I
guess is "I turned towards the east").
