If by 'Greek Orthodox' you mean the Eastern Orthodox Faith (of which Greek Orthodoxy is a part) then it began in the year 33 AD. If you are referring to the Church of Greece, then it began in the year 1850. However, Orthodox Christianity existed in Greece since New Testament times (from St Paul's travels to Athens) and for most of its history, Greece came under the jurisdiction of the Ecumenical Patriarchate of Constantinople. The name "Greek Orthodox" should not be used to describe the whole Eastern Orthodox Church. People who are Greek and Orthodox belong to the same Orthodox Christian Faith. There is no nationality in the Orthodox Church. It is open to people of all backgrounds, races and cultures.
Depends what kind of orthodox you mean. Orthodox Jews wouldn't really be getting married in a church. Greek orthodox probably have a Greek Orthodox church.

Muslim man must marry a Christian woman in a church if she wants that.

If you mean religion, Armenians by majority are Orthodox Christian. They were the first nation to accept Christianity.
What do you mean by this questions? If you refer to religion, Romanians are Eastern Orthodox. I was born in Romania, but I do not understand what you mean by "What do Romanias follow?"
