   • 1885, Frances Mabel Robinson, Mr. Butler's Ward, Vizetelly, page 95:

     Deirdre, it seemed to him, was the most beautiful name in the world. But Mrs. Stanley had different views on nomenclature. She had never, she declared, heard so utterly preposterous a name. […] "Theatre and saltpetre are both spelt that way, Arthur; depend upon it, it is Deirder - a sort of peasant name like Darby and Biddy, a corruption of something else."
