Meaning and history
Daria is the feminine form of Darius. Saint Daria was a 3rd-century woman martyred with her husband Chrysanthus under the Roman emperor Numerian. It has never been a particularly common English given name, and in Russian it is more often transcribed as Darya.
Daria moved from #741 to #826 for girls between 1998 and 1999. Its highest annual birth count came in 1998, with 294 births.
