Football great Brett Favre single-handedly kept this name in the limelight, though it continues to sink in popularity.

Dustin's popularity in recent years has probably had more due to its similarity to Justin than to idolization of Dustin Hoffman -- himself named after silent screen cowboy star Dustin Farnum -- who certainly was the one to put it on the name map. In recent years, golfer Dustin Johnson has brought fresh renown to the name. Dustin is a character in Netflix hit Stranger Things. After decades in the spotlight, Dustin feels like a classic rather than an upstart. It peaked in the Top 50s in the 1980s.

Among the Top 20 names of the 1990s, today's Courtney is more apt to be the babysitter than the baby. Courtney has dropped since its peak at Number 17 in 1995. Familiar from Courtney Love and Courtney Cox.

The straightforward Erica is a Norse feminization that was long associated with the complex, mega-popular character Erica Kane, played by Susan Lucci for decades on the soap opera All My Children.

Jared is an Old Testament name that has been popular for decades--it was revived in the sixties via TV westerns-- and is still an appealing option.

Ruby, Gemma and Pearl are fashionable alternatives, but nowadays Crystal could actually be a more unexpected choice for your little gem.

Brittany first arrived on the US popularity list in 1971, and rapidly zoomed up the charts, in the Top 100 a decade later. By 1986 it had entered the Top 10, becoming the third most popular girls’ name in the country by 1989.
