'Lord Carberry' did indeed take part in the 1914 Schneider Trophy event at Monaco, flying a Deperdusion. Alas he retired on lap 3 due to engine problems. Full details of the race and his involvment can be found in the Schneider Trophy Story by Edward Eaves.
The 1933 edition of Who's Who in British Aviation..gives the following details...Carberry John Evans 'Private owner of aircraft, born Ireland May 1892. educated at Osborne Naval college and Leipzeg Germany. Holder of B Licence and 2nd class Navigators Licence. Served in RNAS during WW1. club Royal Aero. Address Pebble Beach California and Nyeri, Kenya'
Of interest I trust.
