Meaning and history
Adéla is originally a short form of names beginning with the Old German element adal, meaning “noble,” from Proto-Germanic *aþalaz. The name was borne by Saint Adela, a 7th-century Frankish princess who founded a monastery at Pfalzel in France, and by a daughter of William the Conqueror.
Adela moved from #885 to #936 for girls between 1956 and 1957. Its highest annual birth count came in 1918, with 163 births.
