Miles, which has a permanent veneer of cool thanks to jazz great Miles Davis, is a confident and polished boys' name that's an American classic. Always ranking in the US Top 1000, it's been drifting up the charts for the past half century and now ranks at its highest point ever, in the Top 50.

Lucas is a Top 10 boys' name with a slightly-less-popular almost-identical twin brother, Luke. Like Elijah and Elias, Lucas and Luke come from the same root and have the same meaning and so feel even more popular than they are.

One of those simple, straightforward English surnames -- and with a presidential pedigree -- that's easy to translate into a first. Chosen by both Kevin Costner and Jessica Alba for their sons, it has been climbing the US charts since 2009.

While John Wayne and Duke Ellington are worthy role models, the reason Duke is currently enjoying a revival and returned to the Top 1000 in 2013 as one of the year's fastest-rising boys’ names is more likely due to the name given to high-profile TV couple Giuliana and Bill Rancic. Christened Edward Duke, he has always been called by his middle name, just as Edward Duke Ellington was. Duke is just one of several aristocratic titles being increasingly used by ordinary citizens.

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.

Cohen is a common last name among Jews and an important spiritual name in the Jewish religion, associated with the hereditary priests who claimed descent from the biblical Aaron. As a result of its religious significance, Cohen is considered by some to be inappropriate to use as a first name, particularly by people with no Jewish heritage.
