Analysis of information sources in references of the Wikipedia article "Yeomen Warders" in English language version.
The conjecture that sense 2 may have had some different origin, e.g. < buffet 'sideboard,' is historically baseless. No such form of the word as *buffetier exists; and beaufet, which has been cited as a phonetic link between buffet and beefeater, is merely an 18th century bad spelling, not so old as beef-eater.
The nickname 'Beef-eaters,' which is sometimes associated with the Yeomen of the Guard, had its origin in 1669, when Count Cosimo, grand duke of Tuscany, was in England, and, writing of the size and stature of this magnificent Guard, said, 'They are great eaters of beef, of which a very large ration is given them daily at the court, and they might be called Beef-eaters.' The supposed derivation from 'Buffetier' (i.e. one who attends at the sideboard) has no authority.
