After discussing specific ethnic groups in Africa, Gomez follows their movement to North America, where they tended to be amassed in recognizable concentrations within individual colonies (and, later, states). For this reason, he argues, it is possible to identify particular ethnic cultural influences and ensuing social formations that heretofore have been considered unrecoverable. Using sources pertaining to the African continent
as well as runaway slave advertisements, ex-slave narratives, and folklore, Gomez reveals concrete and specific links between particular African populations and their North American progeny, thereby shedding new light on subsequent African American social formation.
