Sandies was settled in the 1830s by members of Green DeWitt's Colony. A church was established in 1842, a Masonic Lodge in 1858, and a school was also founded there. In 1886, Tom and Frank Dew opened a store and gin one mile from Sandies. A post office opened in 1894 at the new community of Dewville. After Mrs. C.C. Vernor platted the townsite in 1897, the church and school relocated there. Dewville's population dwindled after World War II, and the post office closed in 1955. Today, a cemetery marks the site of Sandies, while the Methodist Church and the I.O.O.F. Cemetery remain in Dewville.
