Vibrant, sassy, and bubbly, Ruby is a vintage gem that hasn't lost any of its sparkle. Currently popular in a number of English-speaking countries, Ruby is proof of the 100 Year Rule, trending again for the first time since its heyday in the 1910s.

Simple, classic, strong, and versatile, Jane has shrugged off her plain associations to become a short, punchy name with plenty of literary significance. Calling to mind Jane Austen and Jane Eyre, this charming choice is in the Top 300 in the US and The Netherlands, but a currently underused option elsewhere.

Matthew was the third most popular boys' name in America throughout the 1980s and '90s, and is still one of the top boy names starting with M. The New Testament Matthew is the epitome of the fashionable classic—safe and sturdy, yet with a more engaging personality than John or William.

Walter was seen as a noble name in the Sir Walter Raleigh and Sir Walter Scott era, but it then spent decades in baby name limbo. Now quite a few independent-minded parents are looking at it as a renewable, slightly quirky, classic, stronger and more distinctive than James or John, second only to William among the handsome classic boy baby names starting with W.

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.

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 but Anne is still among the most classic names for girls, although others are more likely to choose the original Hannah, the Anna variation, or even Annabel or Annabella.

Considered ultra debonair in the silent-movie era, Gilbert then went through a nerdy phase, a la Gilbert Gottfried. Now though, like Albert and Alfred and Walter and Frank, it could be in for a style revival.

Shirley Temple almost single-handedly lifted the gloom of the Great Depression, and in tribute (and perhaps wishing for a similarly curly-headed, dimpled darling of their own), thousands of parents of that generation gave their little girls her name. In 1935, Shirley was the second most popular girls' name in the country with more than 42,000 babies named Shirley.

Marilla is a names that's familiar via its resemblance to Mary and variations, but also distinctive: It hasn't been on the Top 1000 since the 1800s and was given to only 27 baby girls last year.

Ever since the enormous German cannon was dubbed by Allied soldiers "Big Bertha" in World War I, this name hasn't worked for a sweet little baby girl. But this was not always so. Hard as it might be to imagine now, Bertha was a Top 100 name until the 1930s, and in the 1880s was the seventh most popular name in the land--the equal of Joseph.

Years ago we might have said that this name was unthinkable, but with clunky, old-fashioned names being so popular right now — consider Augustus, Stanley, Wilfred, etc — what's to stop Cuthbert from becoming more wearable? Bertie is a cute (and very fashionable) nickname option for this grand old name, though Curt and Kit might work too.

Out-of-date for a boy, innovative for a girl.
