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.

Diana, the tragic British princess, inspired many fashions, but strangely, not one for her name. For us, Diana is a gorgeous and still-underused choice.

Ryan’s use as a given name was inspired by the surname Ryan, a variation of the Irish O’Riain meaning "son of Rían." Rían is composed of the Irish-Gaelic elements rí, meaning "king" and an, a diminutive suffix. Ryan is considered a unisex name in the US, where variant spellings Ryann and Ryanne are also valid for girls.

The ubiquitous French version of Mary came into the English-speaking world in the nineteenth century.

Unlike perennials William, John and James, Edward is a classic that moves in and out of fashion. This royal Anglo-Saxon standard has benefited in recent years from the popularity of the hot hero of the vampire sensation Twilight — Edward Cullen — who has given his name a new infusion of cool.

Miranda, a shimmeringly lovely, poetic name that was invented by Shakespeare for the beautiful and admirable young heroine of his play, The Tempest, is still a recommended choice even though its popularity peaked in the 1990's, partially as an antidote to Amanda. But while Amanda now sounds dated, Miranda retains a good measure of its charm.

Lincoln cracked the Top 50 for boys' names for the first time in 2016, more than 150 years after the death of its most famous bearer.

Erik is an alternate spelling and the preferred form of the name across much of Europe.

Lucille is a name that had long been overpowered by its link to Lucille Ball, with an image of tangerine-colored hair, big, round eyes, and a tendency to stage daffy and desperate stunts. But with the newfound craze for double-L names like Lily and Lila, Lulu and Luna, and as the choice of Lucille by hipster parents Maya Rudolph and Paul Thomas Anderson, Lucille is breaking free from its old clownish image, moving rapidly up the charts over the past decade after a long nap.

Natalie — a Franco-Russian name — became Americanized years ago and is one of those surprising names that's always ranked among the girls' Top 1000 names in the US.
