Kaiser, as in roll and Wilhelm, appeared for the first time on the US Top 1000 in 2017. It fits the two-syllable -er ending style that's all the rage, and it lends itself to the short form Kai. But we hope this Germanic version of what is essentially a title rather than a name doesn't keep rising on the charts.

Yet another noble name to join King, Prince, Princess, et al. The name Empress was given to over 100 baby girls in the US last year.
