The first Thain of the Shire was Bucca of the Marish, who founded the Oldbuck family. However, the Oldbuck family later crossed the Brandywine River to create the separate land of Buckland and the family name changed to the familiar "Brandybuck". Their patriarch then became Master of Buckland. With the departure of the Oldbucks/Brandybucks, a new family was selected to have its chieftains be Thain: the Took family (Pippin Took was son of the Thain and would later become Thain himself). The Thain was in charge of Shire Moot and Muster and the Hobbitry-in-Arms, but as the hobbits of the Shire generally led entirely peaceful, uneventful lives the office of Thain came to be seen as something of a formality.
