The Warden of Westmarch

[Birdland]

Sam - From "The Encyclopedia of Arda":

The Westmarch, the land between the Tower Hills and the Far Downs, was added to the Shire some years after the War of the Ring. Its first Warden, appointed by Thain Peregrin, was Fastred of Greenholm. The title was hereditary, passed by Fastred to his son Elfstan Fairbairn, and associated from then on with the Fairbairns of the Towers.

Fairbairns - The family of the descendants of Samwise Gamgee, through his eldest daughter Elanor and her husband Fastred of Greenholm. Fastred became the first Warden of Westmarch, a title handed down to his son Elfstan Fairbairn and his descendants. The family seat was at Undertowers on the Tower Hills, so that the family are often referred to as the 'Fairbairns of the Towers'.
