[1] Shortly after buying his freedom, Quamino became a central member of a plan organized by Samuel Hopkins and Ezra Stiles to send Black missionaries to Africa.
Although Hopkins and Stiles hoped to eventually send thirty or forty missionaries, the plan began with just Quamino and Yamma as candidates.
Both Quamino and Yamma knew African dialects in addition to English, an important asset to make them more effective missionaries than many white academics and divines.
In addition to what were likely sincere religious motivations on Quamino's part, the missionary trip would also enable him to see his mother, with whom he had been able to communicate by letter.
The group's fundraising was successful, attracting support from religious figures in America, England, and Africa, including the famous poet Phyllis Wheatley.
