If there should be a third baby

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.

If you feel, as many parents do, that Gabby or Gabi is too harsh a short form for the mellifluous name Gabriella, try Brie, Brielle, or Briella.

Bryony is an unusually strong plant name --the bryony is a wild climbing vine with green flowers --that caught on in the U.K. before sprouting here. The name of the young character in the Ian McEwan novel Atonement is spelled Briony, which is the variation and Bryony the original.

Daisy, fresh, wholesome, and energetic, is one of the flower names that burst back into bloom after a century's hibernation. Originally a nickname for Margaret (the French Marguerite is the word for the flower), Daisy comes from the phrase "day's eye," because it opens its petals at daybreak.

Eliana is a lilting, rhythmic choice, which has caught on in the US and other English-speaking countries, along with many other El-starting names.

Sweet and stylish, with a sporty, energetic undertone, Everly is a name that ticks lots of boxes.

Grace, a simple and pure virtue name which originally referred to divine grace, is a fashionable classic. In the early 2000s, it seemed headed for the Top 10 but pulled back from the upward trajectory, which you may consider a very good thing.

Gwendolen, an ancient Welsh favorite, retired decades ago in favor of the short form Gwen, but now, as in the case all across the naming board, the nickname has faded and the more distinguished original is up for reappraisal.

James is one of the classic Anglo-Saxon names, a stalwart through the ages that is more popular—and yes, stylish—than ever today. It recently came out Number 1 in a poll of America's favorite boys' baby names, and is the most common male name, counting people of all ages, in the US.

June, a sweetly old-fashioned month name derived from the goddess Juno, was long locked in a time capsule with June Allyson (born Ella) and June Cleaver, but is rising again especially as a middle name.

Levi, lighter and more energetic than most biblical names, with its up vowel ending, combines Old Testament gravitas with the casual flair associated with Levi Strauss jeans.

A versatile classic, Lucy is both sweet and solid, a saint's name, and the heroine of several great novels. First fashionable in England and Wales, Lucy is now a popular choice in the US, The Netherlands, and New Zealand.

Margaret is derived from the French Marguerite, which in turn came from Margarita, the Latin form of the Greek Margarites. Margarites was based on the Old Persian word margārīta, meaning "pearl."

This modern name gathers some steam from the wildly popular Isabel.

Lilting and nearly unknown here, with the currently popular ella ending, makes a good Marissa alternative.

Matilda is a sweet vintage name that has been gently climbing the popularity list for the past 15 years, after a half-century slumber. The spunky children's book heroine Matilda is one factor in its rise, along with others of its class like Eloise and Caspian.

The quality of mercy makes this lovely Puritan virtue name a quiet favorite today. Although it was most popular in the late nineteenth century, Mercy is on its way to a comeback -- it rose 143 spots between 2012 and 2013, making it one of the year's fastest-rising names. Right now, it's still stylish and distinctive, a rare and wonderful combination.

If you're looking for a fresher belle name than Isabelle, Mirabelle is lovely, and we also like the extra flourish of Mirabella. And if you want a nature tie, Mirabelle is also the name of a delicate French plum.

Nora is a lovely, refined name that conjures up images of Belle Epoch ladies in fur-trimmed coats skating in Central Park. Long seen as a quintessentially Irish name though its roots are not in Ireland, Nora is a quietly stylish favorite that's tiptoed to the top of the popularity ladder.

Rose is derived from the Latin rosa, which referred to the flower. There is also evidence to suggest it was a Norman variation of the Germanic name Hrodohaidis, meaning "famous type," and also Hros, "horse". In Old English it was translated as Roese and Rohese.
