The Kynoch factory for the manufacture of explosives was built in Arklow, Ireland in 1895. Mr Arthur Chaimberlain of Kynochs visited South Africa in 1907 to find a place to start another factory. 1,400 acres of land were bought at Umbogintwini, and on 24 October 1907, a group of Irishmen (23 workers and their families) from Arklow sailed from Southampton to work as factory hands at the new Kynoch's factory in Umbogintwini. These people lived in Amanzimtoti and Isipingo before the village of Umbogintwini took shape. One of these "Irishmen" (Harry Purves) was in fact originally from Durban, where he was born to Scottish immigrants.
