Natalie — a Franco-Russian name — became Americanized years ago and is one of those surprising names that's always ranked among the girls' Top 1000 names in the US.

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.

Capturing some of the playful elegance of Madeleine, while avoiding any confusion over the end sound, Madelyn is now an established spelling variation of the French classic. Sweet but strong, Madelyn is a versatile choice that lends itself to the almost inevitable nickname Maddy.

This popular form of the even-more-popular Adeline combines the trendy Ad- prefix with the equally trendy -lynn suffix. Adalynn is the second most widely-used form of this popular name next to the classic Adeline. Singer Chris Daughtry named his daughter Adalynn Rose.

Variation of Annabelle.
