Ross also wrote lyrics for the shows at Daly's Theatre. His lyrics to additional numbers for "An Artist's Model" (1895) and "The Geisha" (1896) were successful enough so that Edwardes asked him for major contributions to the rest, beginning with "A Greek Slave" (1898), especially after the death of the theatre's early chief lyricist, Harry Greenbank. These included a series of enormous successes, including "San Toy" (1899), "The Messenger Boy" (1900), "Kitty Grey" (1901), "The Toreador" (1901), "A Country Girl" (1902), "The Girl from Kays" (1903), "The Orchid" (1903), "The Cingalee" (1904), "The Spring Chicken" (1905) and "The Girls of Gottenberg" (1907). In 1901, Ross married Ethel Wood, an actress, and the couple produced a son and two daughters. The family resided in Church Street, Kensington. Also in 1901, he collaborated with his sister Mary Emily Ropes on the children's story, "On Peter's Island".
