More than likely, what type of people were held captive for slave labor at the Ducros Plantation?
Plantations in the American South Plantations were an important aspect of the history of the American South, particularly the antebellum (pre-American Civil War) era. The mild subtropical climate, plentiful rainfall, and fertile soils of the American Southeast allowed large plantations to flourish; where large numbers of workers, usually Africans held captive for slave labor, were required for agricultural production.
Seminole The Seminole are a Native American people originally from Florida. Today, they principally live in Oklahoma with a minority in Florida, and comprise three federally recognized tribes: the Seminole Tribe of Oklahoma, the Seminole Tribe of Florida, and Miccosukee Tribe of Indians of Florida, as well as independent groups. The Seminole nation emerged in a process of ethnogenesis from various Native American groups who settled in Florida in the 18th century, most significantly northern Muscogee (Creeks) from what is now Georgia and Alabama. The word "Seminole" is derived from the Creek word "simanó-li", which may be itself be derived from the Spanish word "cimarrón", menaning "runaway" or "wild one".
