I was thinking of…

I was thinking Charlie meant church, and kirk meant church,

So,

Church Church.

But I looked it up…

French and English form of Carolus, the Latin form of the Germanic name Karl, which was derived from a word meaning “man” (Proto-Germanic *karlaz). However, an alternative theory states that it is derived from the common Germanic name element *harjaz meaning “army”.

So,

Man Church

Or,

Army Church.
