Since when is this a Czech name? Zoya is Russian form of Zoe and Zoja is just another transcription of the same name from Russian alphabet [Зоя]. [noted -ed]

Also a feminine name in Slovenia.

It isn't a Slovene name! Slovene parents just want to be fancy so they give foreign names to their children. That's a horrible fact.

I'm not sure it's a Czech name. Maybe for a very old woman. It sounds more like a Russian or other Slavic name I think.
