The Gillett Grove Town Hall is located in a refurbished one-room schoolhouse on the west side of the Clay County community. Founded incorporated in 1874 and named after area residents the Gilbert brothers, 55 residents call Gillett Grove home according to the 2000 census. In February 2010, area residents overwhelmingly voted to resolve the South Clay school district and its last remaining school in Gillett Grove. Students were separated into other school districts including Spencer, Sioux Central, Clay-Central-Everly, Ruthven-Ayrshire, and Laurens-Marathon.
