Gender Benders

Vintage nickname name, with a down-to-earth country feel. This renewed interest placed Frankie back in the US Top 1000 in 2015 after a 41-year hiatus. For girls, it's a popular choice in England and Wales, Australia, and New Zealand. Drew Barrymore, who helped popularize and glamorize boyish names for girls, has a daughter named Frankie. On TV's Better Things, Pamela Adlon's middle daughter is named Frankie (sister to Max and Duke, both girls).

On the staff of a manor house.

The name of a British town on the Thames that hosts a famous regatta, so it could be an appropriate middle name for the son of boat-lovers.

Climbing the charts for boys, and has just begun to cross over for girls, despite the macho "hud" sound followed by the "son" syllable.

With Isabel getting so popular, parents are searching for new varieties of the name, and Isabeau is one that makes a lovely French twist.

The longer Isabella stays in the Top 10—and it's been there for more than a decade—the more we hear the nickname Izzy (especially if we watch Grey's Anatomy). it's just a matter of time before it stands on its own, as it has as a first name for the daughter of Eddie Murphy and Paige Butcher.

Jackie Kennedy gave this name a lot of style, but it doesn't seem destined for a comeback the way brother name Jack has. Jackie and Jacqueline both peaked in 1961.

Stylish surname way to go if you want to name a girl after a James, and is more substantial than the passé Jamie; it was chosen for their daughter by Chynna Phillips and Billy Baldwin.

The J spelling of this nickname name has always skewed more masculine, perhaps because it relates directly to Jerome but not to Geraldine. But supermodel Jerry Hall, whose full name is Jerry and who has a twin sister named Terry, pulls it off in glamorous style.

Justice is a fashionable word name, used for both girls and boys. Justice has the distinction of being a virtue name without the religious implications of Faith or Grace. It still feels more male than female, perhaps partly due to the classic Roman name Justus, but Justice has become a more common pick for girls in recent years.

Another two-syllable surname zooming up the ladder for boys, and poised to be grabbed by the girls.
