Appealing comedian Aidy Bryant -- born Aidan -- put this energetic nickname on the map when she joined the cast of Saturday Night Live in 2012. Each of the years since then has seen a handful of baby girls given Aidy as a full name. Which makes sense: It combines the elegance and trendiness of the whole Ada/Adaline/Adelaide family with the retro (almost rockabilly?) appeal of names like Hattie. Expect to see it more going forward as Bryant's star continues to rise.
