Biblical name Cain was, until recently, seldom heard outside of the Old Testament and soap operas. Although Cain's murderous actions will always make this name difficult for some, Cain, Eve and Adam's firstborn, was a farmer - making this a good choice for those with farming connections.

Roux is French from a Latin word meaning russet or brownish red; it's also a cooking term for a mixture of flour and butter that forms the foundation of many gravies or sauces.

Cute but cool, fresh but familiar, Ozzy was one of the fastest-rising boy names of 2021 and has continued to rise in the US and the UK ever since.

Mack, when "formalized" with the final k, makes an engagingly amiable choice, a far more uncommon alternative to the ubiquitous Max and Jack, with a nice, every-guy feel.
