Hi Anne,
Click here to read an article which was originally published in
"Familia", the journal of the Ulster Historical Foundation (volume 2, no. 7, 1991), which is published annually.
The article,
"The Irish in South Africa - The Police, A Case Study: Notes" was written by Donal P. McCracken, University of Durban-Westville. The first part starts by saying: "Nineteenth-century South Africa did not attract mass Irish migration, but Irish communities were to be found in Cape Town, Port Elizabeth, Kimberley, and Johannesburg, with smaller communities in Pretoria, Barberton, Durban and East London." A reasonable number of those who worked in the British Colonial Service in the African continent were from Ireland.
Dafanie Goldsmith has a page on her website about Researching in South Africa and quotes McCracken, p.13 which says
"The Irish came as individuals or family groups and in government assisted schemes - some 14,000 between 1823 and 1900.". Click here to read "South Africa’s people: the British A brief look at their history" which was written by Anne Lehmkuhl for
"Generations" - a South African Genealogy newsletter, ISSN 1480-8854. The article appeared in Issue 12. The word
"British" would include Irish people.
