I know that there is a minority Yazidi population in Armenia. I think there's also one on one of the EU councils. Considering where they live, I bet that what you are saying is the case. From what I understand, they are extremely ethnocentric (no converts accepted, no marrying outside clans. They teach that they are direct descendents of Adam, but not Eve. Femenists will despise their theology on this subject), so evangelisation would be near impossible. But then, is our God a Master at doing impossible things?
