: Unfortunately, we sometimes have to take what's stated in THE HOBBIT with a grain of salt. I'm not saying there wasn't really a village of people in the area. Rather, Tolkien just wasn't able to incorporate that reference into the history provided in THE LORD OF THE RINGS. Maybe it's sufficient to say that by the time Frodo and company passed through the terror of the trolls had not abated.

: As for the more ancient dwellers in the region, they do seem to have been defeated and destroyed in one of the early wars with Angmar. I have interpreted the history to mean that Angmar sent an army through Rhudaur because the hill-folk were too few or too weak to attack the Dunedain of Cardolan alone, and the crossing into Cardolan was easier than winning past the forts of the Weather hills.

: The evil hill-folk who seized control of Rhudaur were definitely destroyed. But there is no reason to assume no one else tried to live in the lands south of the Great Road, except that Aragorn seems to imply the district has long been deserted. It's a sticky issue, and I've found myself arguing both sides of it.

The Hill-Folk of Rhudaur seem to have lived cheek-by-jowl with the Dunedain for some time, and it is a possibility that not all of them threw in their lot with Angmar. A parallel could be drawn with the Folk of Bor in the First Age who remained faithful, unlike the other Swarthy Folk, to their Edainic and Elven hosts. Any "Faithful Hill-Folk" could have migrated south or west from Angmar control or merely sequestered themselves in the mountains, which is a difficult terrain for any power to excercise complete control over. All the major peoples inhabiting Eriador: Dunedain (and possibly assimilated Beorians), Hobbits, Gwathiurim (Breelanders and Dunlendings), and Forodwaith all seem to have left at least relict populations even at the end of the Third Age. On this count alone I think there is a distinct likelyhood that, in some form, Hill-Folk still abided in the Rhudaur area.
