Bucca of the Marish
Around 379 by Shire Reckoning, some four years after the fall of the North-kingdom, the Hobbits of the Shire elected from their midst one Bucca of the Marish as the first Thain. He was to rule the land in the King's stead. Little else is known about him, other than that he brought peace and prosperity to the Hobbits.
The word Bucca is Old English for "he-goat". The Westron version of his name was Gamba.
