Robert was the Number 1 boys' name in the US in both 1925 and 1950, and in fact was in the Top 25 for more than a century, giving it true classic status. Strong if not quite stylish, Robert remains in the Top 100 for baby boys as a family favorite.

Kate and William shocked the world when they announced that they'd named their third child Louis, or Prince Louis Arthur Charles, to be more precise. But we've been predicting a comeback for this classic name for a long time.

Helena is one of those classic names that just misses making the US Top 1000 girl names for its entire history, falling off for a single year in 1992. Since then it's been drifting lazily up the charts, and makes a perfect choice if you want a name that both fits in and stands out.

Iconoclasts though we may be, we like Fred, we like Frank, and we like George, which was among the Top 10 from 1830 to 1950, when the number of little Georges started to decline. Solid, strong, royal and saintly, yet friendly and unpretentious, we think that George is in prime position for a comeback, especially since it was chosen by Britain's royal couple.

Since this was the name chosen by the late Roman Catholic pope in 2013, Francis has come into the spotlight.

A Top 10 name from the 1880s until the 1920s, Frank has been falling for decades but last year reversed course for the first time in a century, edging up the popularity list a few notches. And Frank still has a certain warm, friendly real-guy grandpa flavor that could come back into style, like other such choices as Jake and Jack.

Rupert is a charming-yet-manly name long more popular in Britain (where it's attached to a beloved cartoon bear) than in the U.S. Yet we can see Rupert as a more stylish, modern way to honor an ancestral Robert.

Mary is the English form of Maria, which ultimately was derived from the Hebrew name Maryam/Mariam. The original meaning of Maryam is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).

Helen is a name that has connoted beauty since ancient times – Helen of Troy was the the mythological "face that launched a thousand ships," over whom the ten-year Trojan War was fought.

Maude, also spelled Maud, is a lacy, mauve-tinted name that was wildly popular a hundred years ago, but has been rarely heard in the past fifty. Some stylish parents are starting to choose it again, especially as a middle.

Ann, the name of the sainted mother of the Virgin Mary, was among the top girls’ names for centuries, in both the original English Ann spelling and the French Anne. Both left the Top 100 around 1970 and show no signs of returning, with Anne is the middle of the US Top 1000 and Ann dropped out of sight.
