The Suite Life of Zack and Cody

In the early 1990s, Cody was in the Top 25 most popular boys' names in the USA; but it has been in decline since then. It retains a greater degree of popularity in the UK, however. Cody might be short for Dakota but despite its nickname feeling, it's a name of its own.

Cole -- a short name that embodies a lot of richness and depth -- has long been associated with the great songwriter Cole Porter. It's quite popular in Scotland.

Dapper-sounding choice with old American roots (Dabney Cosby was a 19th century Virginian architect who worked with Thomas Jefferson on some of that state's most iconic buildings). Dabney Montgomery was Martin Luther King Jr's bodyguard, giving this name yet more American history depth. Dab is a sweet nickname option for this name.

An early and still one of the most popular unisex names, also a place name and name of a Native American people in the northern Mississippi valley, which makes it a controversial baby name choice. While the popularity of Dakota is trending downward for both genders, it's one of those rare genuinely gender-neutral names that is used for nearly equal numbers of boys and girls.

A Native American tribe name which is found in the names of two US states, Dakota was one of the first trendy nineties place names, but is now flagging a little in popularity. The cultural question around using a Native American tribe name as a baby name may be partly to blame.

This name found in both Celtic and Scandinavian mythology has gone from all-boy to almost all-girl, retaining a strong, unisex quality. However, it has dropped following its three-decade heyday from the 1960s to the 1990s.

Daniel is one of only a handful of male names that sounds both classic and modern, strong yet approachable, and popular but not cliched. It also has a solid Old Testament pedigree. The only real downside: There are about 10,000 Daniels named each year, making it a less than distinctive choice.

A diminutive of Daniel that's been immortalized in odes ranging from 'Danny Boy' to 'Danny's Song.'

A modern(ish) invented name, only in widespread use since the 20th century. It is a combination of the English word darling and the popular midcentury suffix -lene.

Darrell and all its variations was a trendy name in the 1950s and 1960s, an update on David and Daniel that began to fall out of favor by the 1970s and fell out of the Top 1000 completely at the turn of this century.

David is an enduring worldwide classic, used from ancient times to the present day.

Melodic and lively, Delilah has cut itself (mostly) free from its treacherous past to become a contemporary favorite.

Variation of Derek.

The energetic Diego is rising rapidly along with a lot of other authentically Spanish baby names that work perfectly well with surnames of any origin.

A perennial classic in the Netherlands, short-and-sweet Dirk is starting to feel like a fresher alternative to cousin Derek.

A relatively common surname, Dixon would be an inventive way to honor an ancestral Richard or Dick, the X form a lot livelier than the Dickson spelling, just as Dix is a more modern short form than Dick; it would be right at home alongside Dax and Jax.

Much fresher Irish imports available for colleens now.

Drew, which projects a polished, somewhat intellectual impression, is rapidly becoming the Andrew nickname of choice, replacing the past favorite, Andy. It is fully capable of standing on its own, which it has for many decades, non-stop since 1942.
