Kilian

Kilian is a Germanic name that originated as a compound of the elements 'kil' meaning "church" and 'an' meaning "protector".

The name can be interpreted to mean "protector of the church" or "one who guards the church".

Kilian was the name of an Irish missionary who traveled to modern-day Germany in the 7th century and was eventually martyred for his efforts to spread Christianity.

While the name has been used historically in German-speaking regions, it has also gained popularity in other parts of Europe and beyond as a unique yet traditional boy's name.
