My grandma can beat up your grandma

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.

Old Norman name last current in the 1930s, and firmly in our 'so far out it will always be out' category – despite its appearance as a Hogwarts student in Harry Potter. This is the full first name of P.G. Wodehouse's inimitable Bertie Wooster.

This name of famed philosopher, mathematician and Nobel laureate Bertrand Russell becomes slightly more plausible with the French pronunciation, bare-TRAHN. Another noted bearer is French director and screenwriter Bertrand Tavernier.

Although she declared her independence as far back as the reign of Elizabeth I--Good Queen Bess, Bess now sounds less passé than Beth or Betsy.

After a century of association with horses and cows, this name just could be ready for revival by a fearless baby namer -- after all, it did happen to Jessie and Becky.

This Elizabeth nickname has a decidedly retro feel--think Betsy Ross and the Betsy Wetsy doll-- once seen as a perkier, younger-sounding alternative to Betty. But with Betty on the brink of a comeback, pigtailed Betsy could return as well.

Combine the popularity of Betty White and Mad Men's glamorous Betty Draper Francis, with the residual sweetness of Ugly Betty's Betty Suarez, and the result is an impending return of the name. It's got presidential cred via Betty Ford and feminist history through Betty Friedan.

In the Bible, Beulah is a place, not a person, applied to the land of Israel by the prophet Isaiah. The land of Beulah has sometimes been considered a reference to heaven. Beulah began to be used as a given name in England at the time of the Reformation and was used by the seventeenth century Puritans.

The remarkable success of the girls' name Everly makes a revival of the name Beverly seem possible. More commonly a masculine name in the 19th century, it began to be used for girls in the early 1900s, reaching #14 ion the popular names list in 1937. Inspirations: Beverly Johnson was the first African-American model to appear on the cover of Vogue, Beverly Sills was a major American soprano, Beverly Cleary authored the beloved 'Ramona' books, and Beverly Goldberg is the beloved TV matriarch of 'The Goldbergs'.

Birdie was until recently a middle-aged Ladies' Club member wearing a bird-decorated hat --but now it's just the kind of vintage nickname (think Hattie, Josie, Mamie, Millie) that's coming back into style in a big way. Actress Busy Philipps named her baby Birdie (inspired by First Lady Lady Bird Johnson), as did soap star Maura West.

Blanche, which originated as a nickname for a pale blonde and then became associated with the notion of purity, was in style a century ago, ranking in the double digits until 1920. She then had to fight the stereotype of faded Southern belle, a la Blanche DuBois in Tennessee Williams's A Streetcar Named Desire and Blanche Devereaux in TV's Golden Girls. Now all three of the Golden Girls--Blanche, Rose and Dorothy--could be ready for revival, with Blanche sounding like a stronger, simpler alternative to Bianca.

Vintage nickname for Roberta or Barbara, most famously borne by Roberta "Bobbie" in Edith Nesbit's classic The Railway Children. Bobbie is one of the adorable boyish nicknames newly fashionable for girls, with all the appeal of Billie but without the popularity (yet!).

Like Benita, had some popularity in the fifties.

Bonnie is an adorable nickname name, heading back up the popularity list after a 50-year nap. A Top 100 girls' name throughout the rest of the English-speaking world, Americans are later to jump on the Bonnie bandwagon but now it's trending here too.

Buford has lost any charm it once had. Try Beauford instead.

A Caroline abbreviation that was wildly popular with Mom's generation...or Grandma's. At one time it was a name for baby girls born at Christmas. because of its association with Christmas carols.

This ancient name, also spelled Caspar, is finally shedding its ghostly image and moving into the 21st century. Popular in the Netherlands and Scandinavia, where it's sometimes shortened to Cas, Casper could ride the style coattails of cousin Jasper.

Cassius, a Shakespearean name rooted in antiquity, is trending in a major way. It's one of a raft of Cas-starting names for both boys and girls, including Caspian, Cassian, and Cassia, that are enjoying a new moiment in the sun.

One of the most popular nicknames of the fifties and sixties -- and who could forget the romantic heroine of "Wuthering Heights"? -- now largely ignored in favor of Cate or Kate.

Once a powerful Roman clan name, Cecil has lost much of its potency over the years, though it retains a strong presence in the sports and jazz worlds. Past bearers include film giant Cecil B. DeMille, poet Cecil Day Lewis, father of Daniel, and photographer Cecil Beaton. Fictional Cecils appear in Oscar Wilde's play, Lady Windemere's Fan, E. M. Foster's A Room With a View and the film Lee Daniel's The Butler.
