Harmony, one of the more unique virtue names used today, comes from the Greek word harmonia and English word harmony, which Merriam-Webster defines as "the combination of simultaneous musical notes in a chord." It can also be a musical name for parents who grew up singing or playing instruments. Harmony started gaining popularity in the U.S. in the 1970s, but didn't truly catch on with parents until the 2000s. It entered the top-200 for girl names for the first time in 2012 and has been a top-250 girl's name every year since 2010.
