Quadroon, octoroon and, more rarely, quintroon were historically racial categories of hypodescent used in Latin America and parts of the 19th century Southern United States, particularly Louisiana. Quadroon (from the Spanish cuarterón "quarter") denoted someone of one quarter black ancestry: a person with three white grandparents and one black grandparent. Likewise, octoroon denoted a person of one eighth black ancestry, and quintroon (quint- here implying "fifth generation") or, less commonly, hexadecaroon described a person of one sixteenth black ancestry.
