quadroon

1. (dated, chiefly historical) A person considered three-fourths white, having one non-white grandparent.Examples: "There were slow boys and bashful boys, feeble boys and riotous boys, boys that lisped and boys that stuttered, one or two lame ones, and a merry little quadroon, who could not be taken in elsewhere, but who was welcome to the ‘Bhaer-garten’, though some people predicted that his admission would ruin the school."; "1938, Xavier Herbert, Capricornia, Chapter V, p. 63; Chapter VIII, p. 120 https://archive.org/details/capricornianovel00herb Diana was a black quadroon, her father being a blackfellow. He was the father of four quadroons who were regarded as half-castes because the lighter part of their mother's blood was Asiatic, and he was only too well aware of what their future would be should he desert them."datedhistorical
