Agatha Christie's Poirot

Old-time nickname that may follow in the fashionable footsteps of cronies Jake and Sam.

Abraham is among the most classic baby names that's still widely-used today, popular for its references to both the Bible and American history. The Biblical Abraham was the first of the Old Testament patriarchs and is considered the founding father of the Jewish people. He was originally named Abram, until, according to Genesis, he was told, "No longer shall your name be Abram, but your name shall be Abraham, for I have made you the father of a multitude of nations."

The French spin on the name of the great Homeric hero with the vulnerable heel seems somewhat more portable into the modern world.

Ada is one of the classic baby names for girls that is suddenly super stylish again. A favorite at the end of the nineteenth century, Ada is an alternative to the over-popular Ava. Ada is also part of the trend toward simple, old-fashioned names beginning with a vowel, like Ivy and Ella.

Adam -- a primal Old Testament name -- was revived as a 1960s cowboy name. Adam is not as popular as it once was and feels ready for a respite, replaced by newer A names like Aidan/Aiden, Avery and Axel. Its most prominent current bearers include Adams Sandler, Levine, Brody and Driver -- who plays a character named Adam on Girls.

A vibrant variation of Adele, with a bit of extra flair from that "-a" ending. It could join the army of popular A girls' names, especially with its tie to the success of singer Adele.

Agnes is the Latin variation of the name Hagne, which itself derived from the Greek word hagnos, meaning "chaste." In medieval times, St. Agnes was a very popular saint, leading to its popularity as a girl's name. Agnes Grey is the title of one of the two novels written by Anne Brontë.

This variation of Ahmad is one of the most popular Arabic names among Muslim families the world over and is now the most used spelling in the USA. It shares the same root as other popular Arabic names, including Muhammad and Hamid.

In its three most popular spellings -- Alan along with Allen and Allan -- this midcentury favorite has tended to skew older. It was a Top 100 name from 1938 to 1971, peaking at Number 40 in 1951. Alan has had leading roles on recent TV, in shows like Two and a Half Men, 24 and Boston Legal.

Albert has acquired a new gloss as one of the top royal baby boy names, a considerable upgrade from its serious, studious image (think Einstein, Schweitzer).

Alec, though an old nickname for Alexander, is much fresher sounding than Alex, with the additional advantage, at least to some parents, of being distinctly male (there are as many girl Alexes these days as there are boys). While Alec has a clipped British image, it's actually one of the classic Greek names for boys, by way of father name Alexander.

Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.

Alfred is up off his recliner! If you're looking for a path to Fred, you can go directly to Frederick or take the long way around with the so-out-it's-in-again Alfred. Alfred is quite popular in several European countries, especially England and Wales, Norway, Sweden, and Denmark.

This is one of the ninety-nine attributes of Allah, deemed by Muhammad to be a recommended name for a male child. In this country, it's been primarily associated with boxing immortal Muhammad Ali, known as "the greatest." But Ali is also one of the most popular unisex names for both boys and girls.

Alice is a classic literary name that's both strong and sweet, ranking in the US Top 100 and popular throughout the western world. Alice is derived from the Old French name Aalis, a diminutive of Adelais that itself came from the Germanic name Adalhaidis, which is composed of the Proto-Germanic elements aþala, meaning "noble," and haidu, "kind, appearance, type."

With many British names invading the Yankee name pool, the sophisticated Alistair could and should be part of the next wave. It debuted in the US Top 1000 in 2016. You have a triple choice with this name--the British spell it Alistair or Alastair, while the Scots prefer Alasdair--but they're all suave Gaelic versions of Alexander. Adopted by the lowland Scots by the seventeenth century, the name didn't become popular outside Scotland and Ireland until the twentieth century.

Amabel is an older name than Annabel and a lot more distinctive. Amabel was a very common name in the twelfth and thirteen centuries, then was revived during the nineteenth century British fad for medieval names.

Amanda may no longer be the most popular girls' name in her class, but she is still among the prettiest and has a lovely meaning. Amanda was one of the romantic-sounding girls’ names that rocketed to stardom in the eighties, along with Samantha, Vanessa, et al.

Amelia is one of the hottest girls' names, a successor to the megapopular Emma and Emily. Amelia, which spent several years at Number 1 in England, is now comfortably ensconced in the US Top 10.

Amy is the English variation of the Old French name Amée—Aimée in modern French. Amée was a translation of the Latin name Amata, which derived from amatus, meaning "beloved." Other spelling variations include Amie and Ami.
