Ancient Irish saint's name that's unlikely, because of its similarity to "ninny," to join cousin Finian in popularity.

Luc is the sleeker Gallic cousin of Luke, and if you want to know the difference between their pronunciations, just watch Kevin Kline's hilarious description in the film French Kiss. Peter Gabriel and Sean Patrick Thomas picked this version for their sons.

This spelling pares Will down to the bare minimum — and why not? It is also a Welsh diminutive of William / Wiliam / Gwilym.

Meical is the Welsh form of Michael, a masculine name with Hebrew origins meaning 'Who is like God?' This question is rhetorical, implying that no one is like God. Pronounced roughly as 'MAY-cal', it represents the unique way Welsh language adapted the biblical name to suit its phonetic patterns. While Michael has been one of the most enduringly popular names across Western cultures, Meical remains relatively uncommon outside Wales, giving it a distinctive cultural resonance. The name carries strong connections to Welsh heritage and language traditions, making it particularly meaningful for families with Welsh roots. Its biblical origins combined with its Celtic form create a name that bridges ancient traditions with cultural specificity.

Powel is a masculine name with Welsh and Polish origins. In Welsh, it evolved as a variant of Powell, which itself derives from the given name Paul (from Latin 'Paulus' meaning 'small' or 'humble'). In Polish contexts, it can be a variant spelling of Paweł, the Polish form of Paul. The name has never achieved widespread popularity in English-speaking countries but maintains a steady presence in Welsh communities and areas with strong Polish heritage. Powel carries an air of distinction and tradition, often associated with lineage and family history. In the United States, it occasionally appears as a surname-turned-first-name, reflecting the trend of using family surnames as given names, though it remains relatively uncommon compared to more conventional variants like Paul or Pavel.
