Possibilities

While theoretically unisex, this surname name has been edging up the girls’ names list, perhaps originally as an Ashley substitute. One quality in Ainsley's favor: It's remained steadily popular -- but not TOO popular -- for more than 20 years now, ranking consistently around Number 400. That makes it stylish and familiar without showing up everywhere.

The goddess name Aurora has consistently been on the US popularity list since the nineteenth century, but has really taken off in the past 30 years. Aurora also enjoys remarkable international popularity, ranking in the Top 100 throughout the English-speaking world as well as in Italy, Spain, Norway, Switzerland, and several other European and Latin American countries.

Avery is a hugely popular name in the US, especially for girls. But while nearly four times as many girls as boys are named Avery today Avery's popularity is starting to soften for girls while it continues to strengthen for boys.

Light and glittery, but with plenty of spirit, Kinsley has risen quickly into the US Top 100. Balanced between preppy and cutesy, it feels like a fresh alternative to Kelly, Kaitlyn, or Kimberly.

The capital of England makes a solid and attractive twenty-first-century choice in the US where it is currently in the Top 1000. Given to nearly 1000 girls and 200 boys each year, it is a unisex option that has been in slow decline since its peak in 2013. Conjuring up images of Big Ben, red phone boxes, and the London Eye for some, but perhaps the rush hour commute and grey skies for others, London is far less popular in the UK and other English-speaking countries.

Riley—an upbeat, friendly surname name—is red hot for girls and still going strong for boys. If you haven't been spending much time around babies recently, you may be surprised to learn that Riley is the most popular girls' name starting with R and also the Number 1 Irish name for girls in the US.
