Adele f
English (from French Adèle): of Germanic origin, representing a short form of various compound names with the first element adal noble. It was popular among the Normans as a result of the fame of a 7th-century saint, a daughter of the Frankish king Dagobert II. It was also the name of William the Conqueror's youngest daughter (c.1062–1137), who became the wife of Stephen of Blois and was likewise revered as a saint. It was revived in England in the late 19th century, being the name of a character in Johann Strauss's opera Die Fledermaus. Its popularity was further reinforced in the 1930s as the name of a character in the novels of Dornford Yates.
