Antiquarian Auctions and to Arnaud Labuschagne at Gandolph's Books)
The book (which is a little worn on the spine and even signed by Agatha in pencil) was actually a thesis "submitted in partial fulfilment of requirements for the Degree of Master of Arts in the Faculty of Arts, University of Pretoria". It covers the life and times of Coenraad De Buys and and been used by many researchers because of it's historical accuracy and it's insight into daily life in the colony.
I have been trying to find out who, if anyone, has copyright on the book as I would like to make it available electronically as a searchable PDF file. If anyone can help with regard to copyright on the book or knows of Agatha's descendants I would really appreciate your help!
