Hey Arnold!

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.

Thaddeus, a distinguished, long-neglected name, has several areas of appeal: a solid New Testament legacy, a nice antique feel, and the choice of several more modern nicknames and international variations.

Cute kid with freckles, bouncing a Spalding ball. Cool couple Helena Bonham Carter and Tim Burton put the name Billy Burton on their son's birth certificate. While the classic William, name of the future king of England, may in fact be German, the nickname Billy along with such other classic short forms as Jim and Joe are authentically English names for boys.

Latinizing Lawrence gives it a whole new lease on life. Like Leonardo, Lorenzo has been integrated into the American stockpot of names, partly via actor Lorenzo Lamas. Other associations are with Lorenzo de' Medici, the Florentine Renaissance merchant prince and art patron, Renaissance artists Ghiberti and Lotto, and the upstanding young man who married Shylock's daughter Jessica in Shakespeare's The Merchant of Venice.

Chef Wolfgang Puck has helped soften this thunderous Germanic name; music-lovers will appreciate its association with Mozart, though the composer's middle name Amadeus is more appealing. With Wolf on the rise, however, and parents looking for bolder options, Wolfgang might just intrigue people with its historical feel .

Eugene is a classic that has rather lost its way. On the one hand, it's a grandpa, even great-grandpa name that hasn't been one of the cool kids recently—or to quote Jim Carrey, who bears this name in the middle spot, "You can never get too cool with a name like Eugene." The hero of Disney's Tangled felt the same way, when he changed his birth name of Eugene to the more romantic Flynn.

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. In fact, it's already a fairly popular choice on Nameberry and a solid presence on the England and Wales charts, where it's featured in the latter half since the 90s.

The cool form of James in the 1970s and '80s for both sexes. Still a more stylish short form than Jimmy, though many parents will want to call James by his entire, not-very-long name.

This nickname for popular and traditional Joseph has a long history of being used as a given name all on its own. Nonetheless, everyone will always assume that Joey is short for the longer form. It might be nice for a potential son to have the option of a more professional and classic name to fall back on.

The name of the last Anglo-Saxon king of England before the Norman conquest, and a name that's long been associated with a pipe-smoking, bespectacled grandpa or uncle.

Strange as it may now seem, the venerable St. Arnold was a Greek by birth, a musician who became a member of the court of Charlemagne. The name is said to have been introduced into Britain by the Normans in the form Arnaud.

Both a saint's name and a presidential one via Gerald Ford—who was born Leslie—Gerald is a quintessential 1930s-40s name, when it ranked as high as Number 19. Hence all those nice middle-aged and senior Jerrys we've known and loved. Gerald has always been popular in Ireland, accounting for the prevalence of Fitzgeralds there. Though not considered stylish, Gerald remains on the popularity charts. Cousin Gerard has a similar profile, Geraldo is the well-used Spanish version, and Geraldine is the most promising of the family, in line to follow the path of Josephine to imminent revival.

As heavy as a marble bust of Beethoven.

Pugnacious and spunky like the young Mickey Rooney and the original Mickey Mouse, but virtually never given to babies today.

Sid originated as a nickname for Sidney, but we like it on its own, a la Sara Quin's and Jason Biggs and Jenny Mollen's sons. Sid Vicious, member of the band the Sex Pistols, gives this name a punk rock vibe.

Stalwart Italian classic, completely at home in this country.

One of those Old World nicknames -- think Sally and Patsy -- that long ago crossed over to the girls' side.

Iggy is the quintessential pop star name, though it's the nickname Cate Blanchett uses for son Ignatius. Iggy does bring any grander-sounding name down to earth.

A grassy place with trees is a nice image to attach to a name.
