England's Kings & Princes

This aristocratic, somewhat formal Germanic route to the popular Leo is a royal name: Queen Victoria used it to honor a favorite uncle, King Leopold of Belgium. Though Leopold sounds as if it might be a leonine name, it's not really a relative of such choices as Leon, and Leonard.

Lionel is one leonine name that hasn't taken off as cousins Leo and Leonardo have, though it did reenter the Top 1000 in 2010 after several years away; it was at its highest point in the 1920s and 1930s.

Octavius, which was at one time used for the eighth child in a family, has the worn leather patina of all the ancient Roman names now up for reconsideration. As a Roman family name, it derives from the uncommon forename Octavus, which designated an eighth son.

Philip, the name of one of the 12 apostles, is still favored by parents in search of a solid boys' classic that is less neutral than Robert or John and more distinctive than Daniel or Matthew and has many historic, royal ties.

A classic old Norman name popular for a thousand years and favored for kings (Richard Nixon was named for Richard the Lionhearted), as well as the hoi polloi (as in every Tom, Dick and Harry), Richard was the sixth most popular US boys’ name in 1925, and was still Number 8 in 1950, but is now much less popular.

Robert was the Number 1 boys' name in the US in both 1925 and 1950, and in fact was in the Top 25 for more than a century, giving it true classic status. Strong if not quite stylish, Robert remains in the Top 100 for baby boys as a family favorite.

Stephen, also spelled Steven, is a strong and likable classic, with the he's-a-great-guy short form Steve. Though not as well-used or fashionable as it was in its heyday -- it was a Top 25 name from 1946 to 1957 -- it's still a widely used name. It remains an even more popular in Ireland.

A solid classic with plenty of history, Thomas strikes the balance between strength and gentleness. A favorite in the UK, a staple in France, and Australia, and never absent from the US Top 100, Thomas feels like a safe bet and a name that fits into any era.

William is one of the most enduring of classic names for boys. It's also among the most popular boys' names, as American parents see it as being ideally conservative yet contemporary, and hands-down the most popular baby name beginning with W of all time.
