 The correct German title of the book of G.C.A. Oldendorp (published 1777) is: "Geschichte der Mission der evangelischen Brüder auf den caraibischen Inseln St. Thomas, St. Croix und S. Jan", in English: "History of the Mission of the Evangelic Brothers on the Caribean Islands St. Thomas, St. Croix and S. Jan" (found by Google)
