Leo is a strong-yet-friendly name that was common among the Romans, used for fourteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

Succinct and sharp, Ira is one of the shortest Old Testament names, belonging to one of King David's thirty 'mighty warriors.' It was widely used in the US from the 1880s to the early 1930s (it was Number 57 on the Social Security list in 1881), but fell off completely in 1993, only to return in 2016. Currently, it is in the latter half of the US Top 1000, given to around 260 boys each year.

Ari, the short form of Ariel (or any other Ari- beginning name, such as Aristotle) stands up better as a boys’ name than its progenitor does. It is also short for Aristotle, as in Onassis, and is a prominent character on TV's Entourage -- the uberagent Ari Gold.

With its sharp, succinct sounds and cool, laidback style, Eli is a popular choice among parents today. Compact and punchy, it is a Biblical name with plenty of charm.

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.

Both Jeb and Jed are very attractive Old Testament short forms with long and bright futures. Jeb's main current association is with the Bush brother and former governor of Florida, but the name was a mainstay on early TV westerns, and then went upscale as the nickname (his birth name being Josiah) of the President on "The West Wing."

Old-time nickname that's following in the fashionable footsteps of cronies Jake and Sam. Abe feels both fresher and cuter -- which is maybe the same thing? -- than those choices right now. You can also get to Abe via Abel, which may prove a friendlier formal name than the gray-bearded Abraham.
