Vienna is one of the more popular of the European place-names, with a particularly pleasant sound, evoking elegant images of the Blue Danube, of castles and cafes, sweets and sausages and Strauss waltzes—and Sigmund Freud. It could be a possible substitute for the popular Sienna or Vivienne, though it has been climbing the charts itself.

Emmeline is an Emma relative and Emily cousin that is destined for greater use in the wake of the megapopularity of those two names. A recommended Nameberry fave, Emmeline hopped onto the US Top 1000 in 2014 for the first time ever. While it is genuinely an old name, it was rarely used a century ago; only 17 baby girls were named Emmeline in 1915, the same number as were named Ernie!

Celestia is a heavenly name that sounds more ethereal than Celeste, Celestia might make a distinctive, feminine choice if your taste runs toward names like Angelina and Seraphina.

Aviana is a name that's like the megapopular Ava and Ariana, but not quite as popular as either. It entered into the mainstream back in 2010 however, after actress Amy Adams chose it for her daughter, fulfilling her desire to choose a "normal" name after all, even if it didn't seem like that a decade ago.

Sapphira is a lovely name which unfortunately has an unsavory Biblical history. The New Testament Sapphira was killed by God for lying about a tax payment.
