The popularity of the name Eleanor in England during the Middle Ages was due to the fame of Eleanor of Aquitaine, as well as two queens of the following century: Eleanor of Provence, the wife of Henry III, and Eleanor of Castile, the wife of Edward I. More recently, it was borne by first lady Eleanor Roosevelt (1884-1962), the wife of American president Franklin Roosevelt.
The name was introduced to the English-speaking world by E. D. E. N. Southworth's novel Gloria (1891) and George Bernard Shaw's play You Never Can Tell (1898), which both feature characters with a Portuguese background [1]. It was popularized in the early 20th century by American actress Gloria Swanson (1899-1983). Another famous bearer is feminist Gloria Steinem (1934-).
This name was not regularly given to people until the 19th century [4][3]. It was used by George Eliot for a character in her novel Daniel Deronda (1876).
