Divine or valley
Dyonna is a modern American variation likely derived from the Latin name Diana, meaning 'divine,' or the English name Dionne. It may also be influenced by the Greek name Dionysius or the Old English word for 'valley.' Its usage is rare and often chosen for its unique phonetic appeal.
