Will Whitfoot
From Tolkien Gateway
Will Whitfoot was the Mayor of Michel Delving (and therefore of the Shire) at the time of the War of the Ring. He was renowned as being the fattest hobbit in the Westfarthing, and was affectionately referred to as "Old Will" or "Old Flourdumpling". He was one of the first to be placed in the Lockholes during Sharkey's reign in the Shire, but survived the experience.
