Adeline's has a lovely, old-fashioned "Sweet Adeline" charm, and is a less-used cousin of the trendy Madeline.
Adeline was introduced to England by the Normans in the eleventh century, was very common during the Middle Ages, then vanished until the Victorian Gothic revival.
The song "Sweet Adeline" as an old barbershop quartet favorite. JFK's grandfather John F. Fitzgerald, mayor of Boston, made it his theme song, and Mickey Mouse serenaded Minnie with it in a 1929 cartoon.
Pronounced ad-a-line in America, it's usually ad-a-LEEN in France.
