§ Of the Coming of Men into the West The Silmarillion

Soon after the departure of Felagund the other Men of whom Bëor had spoken came also into Beleriand. First came the Haladin; but meeting the unfriendship of the Green-elves they turned north and dwelt in Thargelion, in the country of Caranthir son of Fëanor; there for a time they had peace, and the people of Caranthir paid little heed to them. In the next year Marach led his people over the mountains; they were a tall and warlike folk, marching in ordered companies, and the Elves of Ossiriand hid themselves and did not waylay them. But Marach, hearing that the people of Bëor were dwelling in a green and fertile land, came down the Dwarf-road, and settled in the country south ; and east of the dwellings of Baran son of Bëor; and there was great friendship between those peoples.
