The earliest dated reference Difford's finds is a Tequila Daisy at a Tijuana bar in July 1936, and the first use of the name Margarita is a September 1953 California newspaper describing the drink in Ensenada. Mexican claimants include Danny Negrete in Tehuacan in 1936, Pancho Morales in Ciudad Juarez in 1942, Danny Herrera near Rosarito around 1948 and Margaret Sames in Acapulco in 1948. None is proven; the border region is the consistent setting.

A beer with lime, salt and hot sauce that Difford's places in Mexico sometime in the 1940s, with the name read as mi chela helada, my cold beer. No inventor is named and the San Luis Potosi club story told elsewhere is not on the page. The simpler Mexico City serve of lime and salt with lager and the Clamato michelato show how loosely the name is used.
