The name derives from the Old French word "flaon", introduced into English after the Norman Conquest of 1066, and adopted into Middle English as "flaun, flawn", The 15th Century printer William Caxton's "Boke for Travellers" mentions these pancakes: "of mylke and of egges, men make flawnes", while "flat as a flawn" was the medieval equivalent of the modern "flat as a pancake". The surname development in London includes the following examples: Margaret Flawne (1577), Richard Flanne (1598), George Flaune (1602), and John Flan (1604). Another modern surname to derive from this source is "Flanner", from the Old French "flaonnier, flaunier", maker of flawns. The marriage of Michael Flawn and Elizabeth Lovell was recorded at St. James's, Duke's Place, London, on October 11th 1692.
