History
Sank's name was bestowed by Jasper Cooper, who owned a store there and had applied for a post office in 1915. In choosing the post office's and community's name, he decided on the name Sank because it was the nickname of a friend and prominent man in the community, "Sank" Fowler.  The post office was in operation between 1912–1920, and 1925–1954.
