If you like Theodore you may love

A favorite of British novelists including Evelyn Waugh and P. G. Wodehouse, Ambrose has an air of blooming well-being and upper-class erudition. It comes from the same Greek root as 'ambrosia', the food of the gods, said to confer immortality.

Arthur, once the shining head of the Knights of the Round Table, is, after decades of neglect, now being polished up and restored by stylish parents, inspired perhaps by the new generation of royals. Arthur has led the list of possible names for the young British princes, chosen as a middle name for Prince Louis, son of William and Catherine, Prince and Princess of Wales.

Bennett is Ben with a bow tie, kind of a cross between Benjamin and Beckett. It's been trending up on the popularity charts in recent years, and its choice by The Unbreakable Kimmy Schmidt's Jane Krakowski could shoot it even higher.

The sophisticated Edmund and its nearly-identical French twin Edmond are coming out of mothballs now that Edward, inspired by Twilight, is once again a hot name.

Historically, the French and English name Florence was used for both sexes. And Florent is a steady classic in France, booming there in the 1980s. Maybe it's time to import it, and show that boys can be floral too.

Harrison, a name made viable by Harrison Ford, is increasingly popular with parents who want an H name that's more formal than Harry or Hank but doesn't veer into the stiff Huntington-Harrington territory.

Harvey, which was brought to England by the Normans and is a version of the French name Herve, is a genial, old-timey name that has been much more popular across the pond. It has been a Top 100 choice in England & Wales since 1997.

Isabel and Isadora are back: could it now be time for a more widespread revival of Isidore? In 2014, both Isidore and Isadore were on the list of fastest-rising names in the US.

Josiah—a biblical name with lots of quaint, old-fashioned charm—makes a much fresher sounding alternative to either Joseph or Joshua, combining the best of both. Josiah is among the several Biblical boys' names that have been on the rise this decade.

Levi, lighter and more energetic than most biblical names, with its up vowel ending, combines Old Testament gravitas with the casual flair associated with Levi Strauss jeans.

This attractively energetic Italian version of the classic Matthew is primed to move further and further into mainstream American nomenclature. Mateo is technically the Spanish version, but many parents in the US use the two spellings interchangeably.

The Reid spelling is the most popular by half, probably because it feels more like a name than Reed, which looks more like a word. It's used occasionally for girls but this name is firmly in the boys' camp.

Reuben is derived from the Hebrew words ra’a, meaning "to see, to understand," and ben, "son." As a phrase it translates to "behold, a son." In the Bible, Reuben is Jacob's first-born son by Leah and the founder of one of the tribes of Israel.

Sleek and smart, with a hint of mystique about it, Silas is a recent addition to the US Top 100. Both mythological and Biblical in origin, Silas joins the ranks of Isaiah, Atlas, Elias, and Sebastian: polished and contemporary feeling names with plenty of history.

One of the many variations of Silvanus, the name of the Roman forest god, and a little-used member of the freshly stylish Sylv- family of names. Silvan is the sleek German and Dutch form.

An approachable mini name that could go on the birth certificate, but may work best as a nickname. Full name options include Thaddeus, Theodore, and Thomas, which was the given name of Abe's son Tad Lincoln. Taddy is a rare alternative to Teddy.

Theodoric feels prehistoric, though with short form Theo one of the hottest names around, this old German names for boys may soon feel new again.

The visibility of actor Wilmer (That 70s Show) Valderrama has highlighted this name, but it's not likely to spread because of its similarity to the feminine (and dated) Wilma.
