The town site of Sherwood was homesteaded by Bert C. Loomis. Loomis deeded to the land to Sherwood H. Sleeper, who subsequently deeded the land to the Northern Town and Land Company or Corporation, who surveyed it into lots. A site for a town was purchased by Sherwood H. Sleeper in the summer of 1904 on the NE quarter of Section 12, Range 85, Township 163. On August 4, 1904, the surveying and platting was begun and the town site plat was filed in Imperial Ward County on September 6, 1904. The town was named Sherwood. The earliest post office of Colquhoun was located on the west side of the township, five miles from the present site of Sherwood, on what was the Maurice Walsh farm. This was known as the “Nina” Post Office. The late C. A. Verry of Minot was instrumental in getting the “Nina” Post Office located in Calquhoun. The postmaster at the Nina Post Office was O. H. Moon. There was also a post office in Eden Valley township called the “Bolacker” Post Office. Mrs. Alexander was the postmistress there. Later, both the Nina and Bolacker Post Offices were moved to the present site of Sherwood with Mrs. Alexander as postmistress. Rural free delivery was established in the fall of 1904 with Fred Cool, Charlie King and Henry Hurdelbrink as mail carriers. Sherwood was organized as a village in April 1905.
