The Biggar family, Alexander Harvey Biggar (29 October 1781 – 27 December 1838) and his two sons Robert (12 September 1813 – 17 April 1838) and George (20 February 1820 – 17 February 1838), were pioneer traders at Port Natal, in what was to become the Colony of Natal. Subsequent to the massacre of Retief's delegation, they became involved in the exchange of attacks between Zulus and settlers. Although contributing to the overthrow of Dingane, all three lost their lives in the conflicts of 1838. Alexander's grandson John Dunn became a well-known Natal pioneer in his own right.
