Baby Number 3... Need a sibling set

Quinn is one of the first popular Irish unisex surnames, a strong and attractive choice on the rise for girls but still popular for boys. Quinn was used for about 3000 baby girls and 700 boys in the US last year.

A literary name figuring in the story of Ben Hur and the novels of Anthony Trollope that has the feel of Roman antiquity that is beginning to appeal to many parents. Quintus was one of only about twenty male first names in ancient Rome, and was often (though not exclusively) used for fifth sons.

Supermodel Christie Brinkley launched an entire name genre when she picked this breezy occupational name for her daughter in 1998, and it has become more prevalent in recent decades. The Saylor version, which you might consider a spelling spin or a surname-name, is now among the Top 500 names for girls, given to three times as many baby girls as the Sailor spelling. Counted together, Saylor and Sailor were used for about 1000 baby girls in one recent year in the US, versus about 100 boys.

There's definitely a cold front of names for winter babies moving in, with Summer, Spring and Autumn giving way to Winter--plus North, January, Frost--and Snow. This name feels brisk, fresh, pure, evocative -- and magical. A haunting middle name choice.

With related choices such as Lark and Phoenix gaining popularity, why not Sparrow? Though it's usually thought of as a female name, Nicole Richie and Joel Madden chose it for their son.

Most familiar as the surname of the handsome anti-hero of Jane Austen’s Pride and Prejudice, Mr Darcy’s rival in both life and love. He has a brief flirtation with Elizabeth Bennet but the truth about his ill intentions and past misdemeanors soon comes out, and he ends up marrying her flighty sister Lydia instead.

Windsor may have male references, such as Britain's royal House of Windsor and a tie's windsor knot, but this name also has a definite feminine feel, as in Windsor Rose. That seems appropriate, as Windsor is used equally these days for boys and girls. Nicknames might include Win, Wind, Windy, and Winnie.

Fresher, brisker and, yes, cooler than Summer or Autumn or Spring, Winter is now a full-fledged female choice, especially since Nicole Richie and Joel Madden used it for daughter Harlow's middle name, and Gretchen Mol picked it as her daughter's first, as did media mogul Sean Parker. Winter continues to be the preferred spelling and has risen in popularity significantly over the past few years.

Wyatt has been hot, which is to say cool, for several years now. With its easy Wyatt Earpish cowboy charm, it's relaxed but still highly respectable.

Brisk, preppy York is an underused classic with the potential to really shine in the 21st century. It's most familiar as a place name — York is a city in England — and surname. New York City and State were named after the Duke of York.
