Gender Benders

Quirky in the way that all Q names are quirky, Quincy was once a buttoned-up, patrician New England name, an image countered in recent years by the talented and ultracool musician Quincy Jones (middle name: Delight; nickname: Q).

A strong, straightforward Irish unisex surname, with a merry glint in its eye, Reagan has been leaping up the popularity lists, to become one of the top girl names starting with R. Some will inevitably link it to President Ronald, but spell it Regan and it's a Shakespearean name: a daughter of King Lear.

Boyish short form of Regina, which is so clunky it's cool.

The Reid spelling is surprisingly more popular than the naturey Reed for both boys and girls, though more than 95% of little Reids are male.

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.

Sam as a name standing on its own was given to only 18 girls in 2021, versus over 400 boys. But as a short form it's appealing and down-to-earth for both sexes, and heard far more often: There were over 2500 baby girls named Samantha in the US in one recent year and more than 8500 boys named Samuel, so you will hear the name Sam a lot more often than you might guess judging by the numbers for this short form.
