The four members of the group were Saint Suttle, Gertie Brown, John Brewster, and Maud Brewster. Suttle and Brewster were called the "Blackville Twins", while their female partners were called "their best girls". The group performed vaudeville in Chicago, along with in Milwaukee and Duluth. One of the groups cakewalk events was named Coontown 400. History 
The origin of the cakewalk was a way for enslaved people to mock their masters, during the Antebellum South-period. "The Two Real Ragtime Coons" was a name given to Suttle and Brown when they performed Vaudeville. The two were involved with many different projects together, with performance and minstrel shows in Chicago, including their involvement in the film Something Good – Negro Kiss (1898).
