Penelope is an unlikely 21st century baby name success story. Off the Top 1000 for 25 years, Penelope jumped back on in 2001 and has been heading uphill ever since, propelled by the trend for mythological names, Spanish actress Penelope Cruz, and some high-profile celebrity babies.

Poppy, unlike most floral names which are sweet and feminine, has a lot of spunk. Long popular throughout the rest of the English-speaking world, Poppy is finally starting to rise toward the top in the US, where it entered the Top 1000 for the first time in 2016.

Magical and earthy, sophisticated but off-beat, Persephone appears as the daughter of Zeus by Demeter in Greek mythology. After she was kidnapped by Hades to be Queen of the Underworld, it was decreed by Zeus that she would spend six months of the year with her mother, allowing crops to grow, and six in mourning, thus accounting for the change of seasons. As such, she is both the goddess of the Underworld and of Spring.

Pearl, like Ruby, has begun to be polished up for a new generation of fashionable children after a century of jewelry box storage.

Several celebs have put it in the middle spot, as in Busy Philipps's Cricket Pearl, Jake Owen's Olive Pearl and Caleb Followill's Dixie Pearl .

A quaint and quirky flower name, until recently considered a bit too prim for most American classrooms but brought back to life in recent years by the attractive character of Primrose "Prim" Everdeen in the Hunger Games series.
