His name was John Carberry. Born John Evans-Freke in 1892, had become the 10th Baron Carbery, inheriting the tile during childhood. He had learned to fly before the Great War and, in 1914, had partcipated in the Schneider Trophy race at Manaco. During the war he joined the Royal Naval Air Service.
John Carberry went on to live in Kenya. He farmed there, owned a number of aircraft and flew extensively during the late 1920s and early 30s.
