      French variation of Latin Sylvia
    • Meaning:

      "from the forest"
    • Description:

      Although Sylvia seems to be having somewhat of a revival among trendsetting baby namers, we'd still opt for the even gentler and more unusual Sylvie. Despite being dated in its native France (where it was popular during the 1950s and 60s), in English-speaking regions it still feels fresh and international without being unfamiliar and has a cosmopolitan, international air. It debuted on the US Top 1000 in 2016.

    • Origin:

      English
    • Meaning:

      "bowman"
    • Description:

      Archer is an Anglo-Saxon surname that feels more modern than most because of its on-target occupational and Hunger Games associations. And it's a nice way to bypass the clunky Archibald to get to the cool nickname Archie.
  11. Rosalie
    • Origin:

      French variation of Rosalia, Latin
    • Meaning:

      "rose"
    • Description:

      Rosalie hit its apex in 1938 and then slid straight downhill until it fell off the U.S. Top 1000 completely in the 1980s, only to spring back to life in 2009 as the name of a character in the Twilight series. The beautiful vampire Rosalie Hale has breathed fresh life back into this mid-century name, and the fact that the character is both sympathetic and relatively minor means Rosalie has the chance to thrive again as a baby name without feeling unduly tied to Twilight.
