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.

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.

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

Ethan is a name that succeeds in being at once classic and fashionable, serious and cheery, strong and sensitive. Given a big boost via the name of the Tom Cruise character in the Mission Impossible film series, Ethan has fallen from its peak at Number 2 in 2009 and 2010, but is still popular in the US along with several other countries.

Samuel has been so popular for so long that it's hard to believe it's still climbing, at its highest point since the 1890s.
