Maud

fem. proper name, from French Mathilde, which is of Germanic origin, literally "mighty in battle;" compare Old High German Mahthilda, from mahti "might, power" (see might (n.)) + hildi "battle," from Proto-Germanic *hildiz "battle" (see Hilda). Matilda (1102-1167), daughter of Henry I, claimant to the throne during the Anarchy, usually is not reckoned among the kings and queens of England.

The name also was late 19c. Australian slang for "a traveler's bundle or swag," hence the expression waltzing Matilda "to travel on foot" (by 1889).

In my electorate nearly every man you meet who is not "waltzing Matilda" rides a bicycle. ["Parliamentary Debates," Australia, 1907]

The lyrics of the song of that name, sometimes called the unofficial Australian national anthem, are said to date to 1893.

surname attested from early 15c., probably in many cases a variant of Mathieson "son of Matthew," but in some cases perhaps "son of Maddy," from the pet form of the fem. proper name Maud. The city in Wisconsin, U.S., was named 1836 for U.S. President James Madison, who had died that year. As the name of a popular dance of 1960 its signification is unknown; supposedly it originated in Baltimore.

Madison Avenue "values and business of advertising and public relations" is attested by 1954, from the street in Manhattan, laid out c. 1836 and also named for the late president. The concentration of advertising agencies there seems to date from the 1940s.
