1911 Encyclopædia Britannica/Octoroon

OCTOROON, or Octaroon (from Lat. octo, eight, formed on the example of quadroon), the offspring of a quadroon and a white; a person having one-eighth negro blood. In rare instances such persons are called tercerons, as being third in descent from a negro ancestor. Occasionally persons are called octoroons when the non-white element is not negro but some other coloured blood.
