Jocko is a masculine name that originated as a diminutive form of 'Jack' or 'John.' It has Scottish roots, where it developed as an affectionate nickname. The name carries a playful, energetic quality and has occasionally been used as a nickname for athletes or performers. Jocko has never been widely popular as a formal given name in most English-speaking countries, remaining instead in the realm of nicknames or informal appellations. The name has sporadic usage in Scotland and other parts of the United Kingdom. It has a distinctive, somewhat whimsical character that sets it apart from more conventional names, appealing to parents looking for something with a light-hearted, friendly quality.

A tough and rugged nature name.

Mingo is a cute nickname of the Spanish version of Dominic. It's not to be confused with Mungo, the name of the patron saint of Glasgow.

Dinand is popular in the Netherlands thanks to a local singing sensation. Dinand is one of many Dutch short forms that come from the middle or end of a name -- think Bas for Sebastian or Hans from Johannes -- rather than from the beginning as is more usual in the U.S. and UK, though we're catching on.

The name of a monk who is the patron saint of blacksmiths -- not a twentieth-century occupation or baby name.

As cool as it is frightening.

Sounds a bit like a nickname in a Dickens novel, but this short form was used in New England a few centuries ago, back when names like Micajah were popular. Both short and long forms are now ripe for revival.

Photographer Newton...or that hard thing you wear on your head.

More than 300 babies have been named Shooter in the US since 2002, which, depending on who you ask, is arguably about 300 too many.

This variation of Rostam might be more English-friendly given its resemblance to the familiar Russ or Russell.
