A Northumbrian by birth, Dr Prideaux Selby was already a middle aged bachelor when he sailed with the Byrnes' settlers to South Africa in 1850. He became the first doctor and Justice of the Peace to the Boer families in the Biggarsberg and lived at “Mooiplaas” for 25 years. He was held in high regard and loved by the Boer families – so much so that the names “Prideaux” and “Selby” were used extensively by the Boer families to name their children.
