Buckland:

Buckland is the eastern-most region of the Shire, located between the far side of the Brandywine River and the Old Forest. This is the home of the Brandybuck Family, the head of the family taking the title of Master of Buckland and acting as the regional leader.

Settled in the year 2340 of the Third Age, or the year 740 according to the Shire Reckoning, by Gorenhad Oldbuck, Buckland was outside the official borders of the Shire until the King Elessar made it an official part of the Shire in the year 42 of the Fourth Age.
