This ancient name, also spelled Caspar, is finally shedding its ghostly image and moving into the 21st century. Popular in the Netherlands and Scandinavia, where it's sometimes shortened to Cas, Casper could ride the style coattails of cousin Jasper.

Jasper and its many international variations, from Kasper to Casper to Gaspard, is finding new popularity.

The surname Costner appeared on the charts in 2021, and it was high time, given the popularity of other financial-themed surnames such as Banks and Ledger. Actor Kevin Costner makes it a familiar choice.
