Gone to the Dogs

Alexis, a one-time exclusively-boys’ name, was more popular than its sister Alexandra for quite a while, but in recent years Alexandra has overtaken it once again. Alexis was a Top 20 girls’ name from 1994-2010 but has experienced a decline in popularity in recent years, though now it's one of the top unisex names.

Extremely amiable, open-sounding surname that's gradually being taken over by the girls.

This Bailey variation is the second most popular spelling for girls, and while the -ee ending does make it more feminine, it feels more substantial in the original form. Bailee and Bayley are two other, less common alternatives.

One of the original unisex Irish surname names, energetic Casey bounced onto the scene in the 1960s, then peaked in the 1980s for both boys and girls. Today Casey is having a resurgence for both girls and boys and re-entered the charts on the girls' side, likely due to the character Kayce Dutton (pronounced like Casey) on the hit show Yellowstone.

Originally a unisex nickname for a redhead -- red hair is called "ginger" in Britain -- or for the name Virginia, Ginger perennially wears pink gingham and spike heels.

Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular boy names starting with J.

Maggie is a cute, earthy short form that has been in style for several decades now, still sometimes used as an independent name by such parents as Jon Stewart. First used in Scotland, it got a large bump in popularity via the 1971 Rod Stewart hit song "Maggie May." Today's Maggie might just as well be short for a more adventurous name such as Magdalena or Magnolia as for the classic Margaret.

Maggie Gyllenhaal was born Margaret.

Max was derived from Maximilian, a Latin name that originated from the Roman family name Maximus. The character name Max in the children's classic Where the Wild Things Are had an impact on baby namers. Max is a widely used name internationally.

Molly is one of the original nickname names, ALWAYS ranking among the US Top 500 girl names since statistics began, in 1880. Molly peaked in 1991 only to rise just as high again in 2011, and though softening retains a good measure of popularity and charm.

Like Peggy and Patsy, the kind of zesty moniker young Judy Garland would sport in her early let's-put-on-a-show flicks. It fell out of favor (and the Top 1000) for a while, but has recently rebounded by reentering the charts in 2013. Expect it to continue gaining traction on the heels of Penelope.

Sadie started as a nickname for Sarah, but their images couldn't be more disparate. Where Sarah is serious and sweet, Sadie is full of sass and fun.

Short for Samuel or long for Sam, Sammy is a sweet midcentury nickname name that we can see coming back.
