Editing Isabel Jay (section)

===Principal soprano===
Late in 1899, Vincent left the D'Oyly Carte Opera Company, turning down the secondary role in ''[[The Rose of Persia]]'' when she was passed over to sing the lead, Sultana Zubeydah, which was given to [[Ellen Beach Yaw]]. Jay was initially given the small role of Blush-of-Morning. Less than two weeks later, when Yaw was dismissed, Jay was promoted to the demanding lead role and received favourable notices as the Sultana.<ref>Cannon, John. {{usurped|1=[https://web.archive.org/web/20160920203224/http://www.gilbertandsullivanarchive.org/sullivan/rose/two_sultanas.html "The Suppressed Saga of Two Savoy Sultanas"]}}, The Gilbert and Sullivan Archive, 15 July 2007, accessed 29 August 2016</ref>

Now the company's leading soprano, Jay played Mabel in ''Pirates'' (1900), again earning good notices, and the title role in the first London revival of ''[[Patience (opera)|Patience]]'' (1901). During the run, she was made an Associate of the Royal Academy of Music.  She then created the roles of Lady Rose Pippin in ''[[The Emerald Isle]]'' (1901) and the Gipsy Woman in ''[[Ib and Little Christina]]'' (1901). She played Phyllis in the first London revival of ''[[Iolanthe]]'' (1901&ndash;1902). She left the company in 1902 to marry the African explorer Henry Shepherd Cavendish, who was later the 6th [[Baron Waterpark]].<ref name=GSNews/><ref name=WhoWasWho/>
