Northrons

the Northrons, also known as the Northmen of Rhovanion or Leidhrim Forod (S.free men of the north) are a group of peoples in Rhovanion.They are for the most Part descendants of the Eriedain, tribes akin to the Edain who did not go to Beleriand or returned to Eriador before it´s drowning.Some Northrons are believed to descend from tribes that came from Eriador and crossed the Hithaeglir in the second Age while others are believed to be the descendants of Men who had lived between the great Greenwood and the Inland Sea of Rhûn since the first Age.

The northrons include the:
 * Beornings, descendants of the Bernings or Beijabar
 * Rohirrim, descendants of the Éothraim or Ehwathrumi
 * the Woodmen of Rhovanion
 * the urban Northmen such as the Lake-men and the Bardings or men of Dale
 * the Gramuz or Plainsmen of southern Rhovanion
 * the Estaravi

during the wars against Angmar several Northron Clans came to Eriador to serve as mercenaries in the great armies of the north, among those are the Vulseggi and the cardolanian Northmen.

sometimes also the Ninniden of the Loeg Firn and the Dorwinrim are counted as Northrons, even if they do not speak rhovanian tongues and have certainly intermixed to large degrees with tribes of Daen and maybe even easterling blood.
