Originally a medieval French diminutive form of Marie, introduced to Britain in the Middle Ages. In some places it was taken as a pet form of Margaret or Margery. As a male name, it is an altered form of the Continental male name Marian, a derivative of Latin Marianus (from Marius), but is now rarely, if ever, used. It was the birth name of the American film star John Wayne (1907–79).
English: habitational name from any of the various places so called. For the most part they derive from the Old English personal name Ella or Elli (see Ellington) + Old English tūn ‘enclosure’, ‘settlement’. One in Berkshire, however, gets its first element from the Old English female personal name Æðelflǣd (composed of the elements æðel ‘noble’ + flǣd ‘beauty’). One in Cambridgeshire has its first element from the personal name Æðelhēah (composed of the elements æðel ‘noble’ + hēah ‘high’). The place of this name in County Durham probably gets its first element from Old English ǣl ‘eel’.
