Captain Duncan Campbell (1781 – 20 December 1856) was a Royal Marines officer and an 1820 British settler from Hampshire to South Africa having sailed on the Weymouth as a leader of a party numbering 28.
The party was to occupy holdings on the Sonderend River, near the mission station of Genadendal, in the district of Caledon.
This industry proved profitable and grew to be the most important of all South Africa's farming activities around 1957.
In 1827 he held the office of civil commissioner / resident magistrate at Grahamstown and Somerset East.
About 1 January 1828 Captain Campbell was appointed to the position of civil commissioner for the districts of Albany and Somerset East – an extremely difficult post by reason of the incessant unprovoked cross-border incursions into the young colony by the blacks .
