Sir John Faulconer Kt. 50 Edward III (1377) = Katherine 4 Richard II.(1381)

It is of medieval origin taken from Old French faulconnier. Anglicized version of occupational name for someone who kept and trained falcons (a common feudal service). Falconry was a tremendously popular sport among the aristocracy in medieval Europe, and most great houses had their falconers.
