Olive Hannibal Coates Palgrave was a botanical illustrator, noted for her richly illustrated 1956 book "Trees of Central Africa".
Background
She was the eldest of at least 5 children of Ada Mary Hannibal and Albert John Alfred Trollip (1857-1943), a descendant of the 1820 Settlers, and a Cradock sheep farmer who lost his entire flock in a snow storm, leading to his moving to Southern Rhodesia in 1895.
Career
His family joined him only in 1900, travelling by train to Bulawayo and then by the famous Zeederberg Coach Company to Gwelo, the Matabele Rebellion and Boer War having delayed their departure. Olive finished school in 1906. They raised a family of three sons, Roderic (Deric)(1917), Keith (1926) and Paul (1929), all of whom regularly joined in excursions to the bush.
Keith"s brother Paul, and Paul"s wife, Meg, provided the photographs used in the book
