From the experts:
Lucienne is a soft and ultra-sophisticated French-accented option in the Lucy family, one that could provide a fresh alternative to such fatigued Gallic choices as Danielle and Michelle.
So if you're looking for a more elegant take on Lucy, this could be it. The original male Lucian is a Latin name while Lucien is the French form and Lucienne is a female spin on that.
