The Sandyman family was a family of Shire-hobbits that owned and operated the Mill of Hobbiton.

Ted Sandyman, son of the elder Sandyman, allied with Saruman's hordes during the War of the Ring and let them remodel his mill. This change in the mill meant that corn was no longer ground and filth was instead poured into the Water.

Those of the Fellowship who returned to their homes in Hobbiton had to fix this problem when rebuilding the Shire.
