Abel, the name of Adam and Eve's unfortunate younger son, compensates with positive connotations: capable, competent, ready and willing. 
 Abel has literary connections to the novels of Dickens and Trollope, and is also one of the few well-known Old Testament names not plagued by overuse. Having been chosen for their second son by Amy Pohler and Will Arnett could give it a real popularity bounce.
 Abel's namesakes include two movie directors, Abel Gance and Abel Ferrara, and a pop singer, Abel Tesfaye, more commonly known as The Weeknd.

In its three most popular spellings -- Alan along with Allen and Allan -- this midcentury favorite has tended to skew older. It was a Top 100 name from 1938 to 1971, peaking at Number 40 in 1951. Alan has had leading roles on recent TV, in shows like Two and a Half Men, 24 and Boston Legal.
 Current bearers include Alan Alda, Alan Cummings, and writers Alan Bennett and Alan Ayckbourn.
Alan is a venerable Celtic name, first used in England in the Middle Ages. We like the Welsh spelling Alun.

Alan

An ancient and highly unusual name; St. Alban -- sometimes also called Albinus or Aubin -- was an early martyr in Roman Britain.  Using an alternate spelling, Alben Barkley was the 35th U.S. Vice-President, serving under Harry Truman.  And Albin is popular in modern Sweden. But only the form Alban has the alternate meaning "from Alba".

Corentin is an intriguing saint's name fashionable in France but virtually unknown here-- which you may consider a big plus. St. Corentin possessed a magical fish that regenerated itself each night, feeding himself and his lucky visitors in perpetuity.

The name of the patron saint of Wales is virtually unknown in the US under this spelling. There were no baby boys named Dewi or Dewie in the US in 2021, though there were 35 named Dewey. Incredibly enough, Dewey ranked among the US Top 1000 for an entire century, from 1887 to 1986, reaching as high as Number 19 in 1898.

The final letter makes the name more unusual and adds some zest.  Downside: Sure to be confusion with Elias.

Evan has a mellow nice-guy image that has kept it popular, while it has been widely used in Wales since the nineteenth century. And interestingly—and surprisingly—enough, Evan charts highly for boys in France.
 Evan was derived from Iefan, a Welsh version of John. John is ultimately a derivative of the Hebrew name Yochanan, comprised of the elements yo, meaning "God" and chanan, "to be gracious." Evan is actually a Hebrew word itself, meaning "rock."
 
Jenny McCarthy has a son named Evan, and some other modern associations are former Senator Evan Bayh, novelist Evan Hunter, and the movie Evan Almighty. It is also sometimes used for girls, as in actress Evan Rachel Wood.

This cross-cultural name, found in Wales, Brittany, and Spain, is a surprise star in the U.S. in recent years, largely thanks to actor Gael Garcia Bernal. It's especially popular in Texas.

Two prominent literary namesakes make Gregor a somewhat risky choice. On the highbrow side, there's Gregor Samsa, the Kafka character who woke up one day to find himself turned into a cockroach. And then there's Gregor Clegane, one of the most feared and purely evil characters in the world of Game of Thrones. It's a shame, because this earlier form of Gregory, quite common in Scotland, would otherwise make an attractive choice.
