Just been corrected by Paloma and my own Martinez page. Craddock stipulates Curacao or Maraschino in a Martinez but Thomas only does in his Manhattan.

Not according to O. Byron who published the first Martinez recipe in his 1884 ‘The Modern Bartender’. Jerry Thomas omits the Martinez from his 1862 first edition and second 1876 edition but it does appear in the 1887 edition published two years after his death. Vintage cocktail books, including Harry Craddock’s 1930 ‘The Savoy Cocktail Book’ and indeed Jerry Thomas’ 1887 ‘Bar-tenders Guide’ stipulate “Curaçao or Maraschino.” Perhaps an argument for equal parts of both.
