On the history:
"The melody [of "For He's a Jolly Good Fellow" etc.] was originally associated with the Malbrouk song, the words of which appear in a collection of street songs, Chansons, Vaudevilles et Ariettes Choisis par Duchemin, published by Valleyre, on p. 10 under the title La Mort de M. de Marlb'roug; BN. The collection is not dated but is believed to be between 1762 and 1778. The song is also said to have been referred to in a play by Charles Simon Favart, Les Rêveries Renouvellées des Grecs performed and printed in 1779 in Paris, p. 26; however, there is an error in the citation, and the reference cannot be confirmed in the copy at BN.
"Commencing early in 1783, there was a rash of printing of the Malbrouk melody under that title or the title Marlbourouck, or other variation, apparently brought about when a nurse sang it to one of Marie Antoinette's infants as a lullaby about 1781. Mercure de France lists at least 10 printings by different publishers in 1783-1784, not all with words, the earliest of which in May 31, 1783, p. 240, is entitled Air de Marlbourouck, with nine variations for piano, published by Levasseur, Paris; no copy has been located. Other French editions were printed without name of publisher, and there were many early foreign printings. Various contemporary French and other editions are at BN, COP, BM and JF."--(James J. Fuld, The Book of World-Famous Music, 4th ed., Dover, 1995, p. 231)
