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.
Despite such reputable namesakes as composer Arnold Schoenberg, novelist Arnold Bennett and historian Arnold Toynbee, not to mention the former Governator, Arnold's image has been diminished by some nerdy fictional characters, though he is still a genuine classic who might come back along with Arthur and Albert.
We have heard stirrings of fashionable baby Arnolds populating nurseries alongside those named Wilbur and Barney.

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.

Despite the success of so many O-starting <a href="https://nameberry.com/boys-names">boys names</a>--Oliver, Owen, Otis, Oscar--Oswald has not yet shown any signs of resurrection, though he does have the animating nicknames Ozzie/Ozzy and Oz.

Now seen as the chap in the smoking jacket in a 1930s drawing-room comedy, Reginald has actually been on the US popularity list every year since 1880.
 A name that was quite common throughout the MIddle Ages, in the modern era Reginald has been associated—in its nickname form—with star athletes like Reggie Jackson and Reggie Bush, plus it's the birth name of Elton John. In literature, Reginald Wilfer is a character in the Dickens novel Our Mutual Friend; Reginald is also the first name of capable and oh-so-proper butler Jeeves in P.G.
