In later years, additional populations of free blacks began moving to the northwest just beyond the Mount Vernon-Belvedere neighborhood and beyond Seton Hill, along the future Pennsylvania Avenue and Druid Hill Avenue of what became known as Upton. The building was built and financed by the predominantly "colored" Maryland Baptist Union Association, (as opposed to the organization of the Baptist Convention of Maryland) who had generally separated from the white Baptists after often worshipping together in the small building during the colonial days of the late 18th century (although most of the time in upper balconies or separate pews/chairs in the sanctuary), into the early 19th century of the American Republic.
