Caleb is an attractive Old Testament name that has been in the US Top 100 for nearly three decades now. Consistently popular but never too popular, Caleb feels more like a classic than a momentary trend.

Ralph has two diametrically different images: there's the suave Ralph Fiennes-type Brit (often pronounced Rafe), and then there's the Jackie Gleason blue-collar, bowling blowhard Ralph Kramden bus driver. It's all in the eye of the beholder, though its hip factor did rise when it was chosen for his son by cool U.K. actor Matthew Macfadyen.

Connor, the appealing name of an early semi-legendary king of Ulster in Irish mythology, sits firmly in the Top 100 and taken together with its alternate spellings would rank even higher. In its native Ireland the Conor version is one of the highest charting boys’ name.

One of many R- boys’ names that started as a nickname for a redhead, Russell had a measure of popularity from the early twentieth century through the 1950s. But it's now lost much of its color -- except for a few dynamic bearers, actors Russell Crowe and Russell Brand and sports stars Russell Westbrook and Russell Wilson.

Rudy is one of those names that has been consistently in the US Top 1000 since the early 20th century without ever becoming overwhelmingly popular. It peaked back in the 1930s, when it briefly entered the Top 250, though more recent years have seen it make the latter end of the charts. Certainly more stylish than its parent name, Rudolph, which has been relegated to reindeers in English speaking countries, Rudy was given to 300 boys in a recent year.

A 1970s beach boy surfing buddy of Scott, Brad, and Chad, Todd is given to relatively few babies these days.

The fierce image of the Barbarian made a complete turnaround thanks to amiable talk show host O'Brien, making Conan one of the newly desirable Irish choices, a perfect alternative to Conor/Connor.

Most famous as one of the many middle names of Professor Dumbledore from Harry Potter, Wulfric is an earlier form of the medieval English name Ulric. It has also belonged to an 11th- century Earl of Mercia and a 12th-century saint.

Lupin is an unusual flower name with roots in Old French, from the Latin lupinus, meaning "pertaining to the wolf". In the literary world, it's the surname of Remus Lupin, a popular character in the Harry Potter franchise and a werewolf.

Phelan, pronounced FAY-lan or FEE-lan, is an appealing Irish surname name, with a rich history in Irish myth and religious and secular life. One bearer was a fiercely loyal follower of the legendary warrior Finn MacCool, another was a missionary saint.

Medieval name without much of a future.

Properly spelled with a fada in Gaelic (Faolán), this name is the origin of the Irish surname Phelan. It derives from the Gaelic fáel "wolf", plus a diminutive suffix, making this a handsome hidden nature name.

Too many Connors in your neighborhood? This name--spelled with one 'l' or two--is equally authentic and much more unusual.

One of three Cherokee names with the same meaning, along with Inali and Enoli, both male names.

An unusual, energetic surname choice that would make a good Madison alternative. Madigan was a typical police detective series of the 1970s, starring Richard Widmark.

Derived from a Spanish title of the Virgin Mary, Guadalupe, Lupe has both a spiritual and animal meaning. In relation to its long form, it is associated with a convent in Spain and the appearance of Our Lady of Guadalupe to a Mexican man in the 16th-century. Taken as a stand-alone name, it derives from the Latin word for "wolf", lupus.

Randolph is a timeworn classic that had its last hurrah in the 1940s, when Randolph (born George) Scott was starring in westerns, but then was probably done in by its tricky nickname Randy (which, strangely enough, was itself a Top 50 name in the fifties and sixties).

Conroy is one Con name that feels a bit dated, though perhaps it's so far out it's coming in? Worth consideration if you like Connor but feel it's too widely used.

More commonly a male given name, but Esarosa is used for girls as well and it is no wonder why — this name has lots of potential and nickname options galore.
