Sweet and sparky, youthful yet long-established, this Scottish nickname for Margaret, Mairead, or Mary, entered the US Top 1000 back in 2014 and has been on the rise ever since, replacing the once popular Macy which peaked back in the 2000s. Game of Thrones star Maisie Williams helped propel the name back into the limelight, along with the that of her character, Arya, while singer Maisie Peters has helped keep it in the charts.

This ultrapopular boys' name is rapidly becoming a hot name for girls; admired for its buoyant Irish spirit.

The combination of Emily and Emma's popularity -- and the fact that Desperate Housewives star Teri Hatcher's daughter is named Emerson -- have put this formerly strictly boys’ name, embodying the gravitas of Ralph Waldo Emerson, in the limelight for girls.

An attempt to make this name swing more to the feminine side, though the original Ryan is becoming perfectly acceptable for girls.
