Kylian
Meaning
variant of Kilian, 'church' / 'little churchman'
The story
Kylian is the French spelling of the Irish Cillian, traditionally linked to the meaning little church; Saint Kilian was an Irish missionary bishop who died in seventh-century Germany and is still honored in Würzburg. The modern fame is all one man's. Kylian Mbappé burst into the 2018 World Cup as a teenager, scored in the final as France won it, struck a hat-trick in the astonishing 2022 final that France narrowly lost, and now captains his country while starring for Real Madrid. In France the name had already grown popular before he made it famous worldwide. In the United States it was essentially unused until this century, appearing and growing only in the last two decades, right alongside Mbappé's rise; we cannot prove the connection, but the timing is hard to ignore. Kylian remains a rare, distinctly French pick.
