Whether you pronounce it Mac-cleen or Mac-clayn, this is one of the crispest and most appealing of the Mac names. The Scottish clan Maclean is one of the oldest of the Highland Scottish clans. Trivia tidbit: Sir Fitzroy Maclean is said to have been an inspiration for the Ian Fleming James Bond character.

Seann is a masculine name primarily representing an alternative spelling of Sean, the Irish form of John. While Sean (pronounced 'shawn') comes from the Irish version of the Hebrew name Yochanan meaning 'God is gracious,' the doubled 'n' in Seann might be an Anglicized modification to emphasize the pronunciation or distinguish it from 'seen.' This spelling variation maintains the name's Celtic heritage while creating a slightly distinctive appearance. Though less common than the traditional Sean spelling, Seann has gained some usage in English-speaking countries. The name carries the rich historical and cultural connections of its original form, with links to Ireland and Scotland. Popular in the late 20th century, Sean/Seann remains recognized while no longer being among the most common names.

Classically, the De- prefix indicates "son of," so any variation of this name could work for the child of a dad named Shawn or Sean.

Those "Where's Gretel?" jokes will get old pretty fast.

For a minute or two this sounded more modern than Janet, now equally outmoded.

Jovan, the name of the supreme Roman deity, seems more extraterrestrial now -- and it's also firmly attached to a perfume label. Some parents may see it as a variation of Giovanni, the Italian for John. It is in fact the Slavic variation of John and may be an original way to honor an ancestral John.

High-profile First Daughter Trump bears a nickname for her mother's name, Ivana. But though quite common in Slavic countries, and despite its international appeal, Ivanka is likely to remain a Singe-Celebrity name in the US — the Oprah of the political world — for the foreseeable future. Ivanka's larger impact on names may be inspiring parents to name their daughters after their moms.

Keoni is one of the lesser-used international forms of John, but it has an on-trend sound that many parents may find appealing, perhaps as an alternative honor name. As well as Hawaii, it is also given to one or two dozen boys in California each year.

Yanka is a masculine name with Slavic origins, particularly common in Belarus as a variant of the name Jan (the Slavic form of John). The name ultimately derives from the Hebrew Yochanan, meaning 'God is gracious.' In Eastern European contexts, particularly Belarus and parts of Russia, Yanka has historical usage and cultural significance. The name gained some recognition through Yanka Kupala, the pen name of Ivan Lutsevich, a famous Belarusian poet and writer. While rare in Western countries, this short, distinctive name has a strong, accessible sound that crosses cultural boundaries. The name's simplicity makes it easy to pronounce in multiple languages while still maintaining its Slavic heritage. Yanka offers a unique alternative to more common John-derived names.

With its upbeat Slavic/Scandinavian air, it has the most potential of all the Jan names.

St. JOhn is mainly (but rarely) used by Catholics in England -- there's one in Jane Eyre. This would probably be too cumbersome for most American kids.
