Explorations in Africa 
St Vincent Erskine carried out a number of exploratory journeys in Southern Africa between 1868 and 1875 from Natal northwards into Gazaland and down to the mouth of the River Limpopo. Gazaland (modern day Mozambique and Zimbabwe extending northward from the Komati River at Delagoa Bay in Mozambique's Maputo Province to the Pungwe River in central Mozambique) records  - “Probably the first European to penetrate any distance inland from the Sofala coast since the Portuguese gold-seekers of the 16th century was St. Vincent W. Erskine, who explored the region between the Limpopo and Pungwe (1868-1875).”

St Vincent Erskine's four journeys are reported in the Journal of the Royal Geographical Society, London:
 Journey of Exploration to the Mouth of the River Limpopo, By St Vincent W Erskine
 Journey to Umzila’s, South East Africa in 1871-1872. By Mr St Vincent Erskine, special Commissioner from the Natal government to Umzila, King of Gasa; and
 Two Journeys of Mr St Vincent Erskine in Gasa Land during the years 1873, 1874 and 1875

Later career 
Following his exploratory journeys St Vincent Erskine worked as a surveyor in Natal, the Transvaal and Cape Province. He settled with his family in Cape Town where he died in 1918.

Source material 
St Vincent Erskine’s "My journal on the Limpopo River" and Alice Erskine’s diary are lodged with the University of Natal. Extracts from Alice Erskine’s diary can be found in “Buchanan Family Records, James Buchanan and his descendants". She reports the family living in Kokstad, East Griqualand in 1878 where they were attacked by the Griquas who were in rebellion. St Vincent and Alice Erskine both suffered broken legs when the powder magazine exploded. Alice Erskine required to go to England for treatment to save her leg. Having returned from England and lived in Kostad the family moved a year later to Vryheid, describing the rigours of the difficult journey by ox wagon.

Material about St Vincent Erskine is also held by the National Archives of South Africa which include claims for payment of the work; applications to practice as a land surveyor; to be a magistrate at Inanda Division; applications by Alice Erskine for assistance in the education of her children; references to land transactions and to courts cases involving St Vincent etc. and the Royal Geographical Society archives which are mainly manuscripts for his articles, maps and sketches  and in the UK National Archives including a letter from Major D Erskine (father of St. Vincent Erskine) dated Dec 22, 1880, to Lord Aberdare, asking support for son's application to be employed on the Transvaal survey[RGS/CB6/742].
