History & Origin

Cydnee is one of many creative spellings of Sydney, an English surname and place name traditionally explained as Old English for a 'wide meadow' or 'wide island', or as a contraction of the French Saint-Denis. The C-and-double-e reshaping is a purely modern American touch.

This spelling rose with Sydney's surge in the nineteen-nineties, peaked around 1997, and faded as the naming trend cooled and simpler spellings prevailed. It reads as a distinctly nineties respelling rather than a name on the way back.

Did you know? Cydnee crested around 1997, at the peak of Sydney's run as a fashionable surname-style girls' name.
