The Griqua are often considered to be a racially and culturally mixed people whose origin goes back to the intermarriages or sexual relations between European colonists in the Cape and the Khoikhoi already living there in the seventeenth and eighteenth centuries. This notion apparently derives from the name given in 1813 by Rev. John Campbell (London Missionary Society) to a mixed group of Grigriqua (a Cape Khoikhoi group), 'bastaards', Koranna, and Tswana living at the site of present day Griekwastad [1] (formerly "Klaarwater"). According to Isaac Tirion[2], by 1730 the Grigriquas already lived in this northeastern section of the Cape Colony.
