Plus, Jonah comes with a ready-made nursery-decorating motif.

Casey is a name with a big wide grin, Irish, friendly, and open, and associated with several American folk heroes--Casey Jones, the engine driver of the Cannonball Express who gave his life to save his passengers, and the legendary Casey at the Bat.

Adam -- a primal Old Testament name -- was revived as a 1960s cowboy name.

Patrick, long tied to a hyper-Irish image, is enjoying something of a renaissance as a stylish classic, as it has long been considered in England. Along with such choices as Charles and George, Patrick has escaped overuse in recent decades.

Aaron is a name of subtle contrasts: an unusual spelling that is easily recognizable; a solid Biblical choice that doesn’t feel exclusively tied to religion; a well-established name for boys but sometimes confused with the girls’ name, Erin; used internationally but with notably different pronunciations; classic like Andrew but not out of place with recent favorites like Weston or Jayden.

Kevin came to the US with the large wave of Irish Immigrants after World War I, hitting the US Top 1000 list for the first time in 1921 and never leaving.

Blake -- an early unisex option -- dropped out of the Top 100 in 2017 for the first time since 1988, but remains a sophisticated choice. And yes, both conflicting meanings of Blake are accurate. It originated as a surname in England derived from a nickname. Much of its masculine image was influenced by the wealthy, silver-haired character Blake Carrington in the massively popular 80s TV series Dynasty. Rosie O'Donnell has a son named Blake.

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.

Colton is a trendy two-syllable choice, with the popular 'on/en' ending.

A name that has a bit of a shouldn't-I-be-a-middle-name sound, though still in use as a first for both genders. Lee might be a good choice if you want something that sounds at once traditional yet modern, unisex but not newly-minted.
