The musical word name Cadence, barely heard a few years ago, seemed to come out of nowhere to zoom up the charts. Some might see it as a trendy feminine relative of the popular Caden. Kadence and Kaydence are also rising.
An early Cadence sighting was in the 1992 Armistead Maupin novel Maybe the Moon, in which the narrator heroine was a small actress called Cadence Roth, nn Cady. January Jones played a Cadence in American wedding.
