*[Papadopoulos][1]* is the most common Greek surname. It means "son of a priest". The female version is *Papadopoulou*. I wonder why. As far as I know, priests don't marry and are celibate, meaning they can't father a child. So, how did this become a common surname? Does the expression "son of a priest" carry another meaning that I'm missing? [1]: https://en.wikipedia.org/wiki/Papadopoulos
