Still Not sure of the relevance but here is what I found
The Greek adjective orthodox (ὀρθόδοξος) is dated to the late third/early fourth centuries, and the derived Latin word (orthodoxus or ortodoxus) was also first used at about that time. There is an earlier verb ὀρθοδοξεῖν, meaning “to have correct beliefs”, used by Aristotle in the Nicomachean Ethics. As far as I know, Aristotle’s coining is original, not based on any other language.
In Christianity, the term originally became popular to describe those groups that adhered to the definition of the Council of Chalcedon (451 AD), even though the Oriental Orthodox churches that you mention are exactly the opposite, not accepting the Chalcedonian dogmatic definition. The Oxford English Dictionary (under orthodox, 3) suggests that this is due to a later assumption that “Orthodox” refers to anybody who was not on the Catholic side at the time of the Great Schism (1054). So it seems that “Orthodox” was first associated with the Eastern Orthodox churches, and only later became applied to the Oriental Orthodox.
For the reasons set out below, I think that the group term “Oriental Orthodox” was invented or at least popularized in the 1960s; and that at least some of the churches in question had Orthodox in their name for some years before that, though probably not earlier than the eighteenth century.
It is a bit hard to distinguish between a church that uses Orthodox as part of its name, and one that merely describes itself as orthodox. Certainly, people have been calling themselves small-o orthodox for centuries, and in some cases that shifted from “we are orthodox” to “we are the Orthodox”. The unambiguous use of Orthodox in the name is comparatively recent, in all cases.

“Orthodox” as a title of the Eastern Orthodox churches
From what I can see, the term “Orthodox” was not used as a distinctive term until many years after the Schism. The more normal way was to talk about the Eastern Church and the Western Church. The everyday usage was “the Greeks”, though this is of course inaccurate since not all Greeks are Orthodox and not all Orthodox are Greek. Meanwhile, Christians in general could be called orthodox or catholic for some centuries, regardless of their east-west allegiance.
For example, in the proceedings of the Council of Basel (1431-5), we read “the Greeks” as the standard term for the Greek Orthodox delegates, as opposed to “the Romans”; but “the orthodox faith” and “the catholic church” are both used to mean Christianity in general.
The Orthodox churches were certainly using the term as part of their identity by 1672, since the record of the Synod of Jerusalem contains many references to Orthodoxy as a tradition and as a communion (eg, talking about “our Orthodox religion”, “Orthodox bishops”, etc.). They were undoubtedly trying to use the term to distinguish themselves from the Roman Catholics, and to a lesser extent the Protestants. But even then, “Orthodox” was not part of the name of the church: the synod talks of “the Eastern Church”, which holds “the Orthodox faith”, but they don’t use the title “Orthodox” for the church itself
Father Hardon’s Catholic Dictionary
“ORTHODOXY. Right belief as compared with heterodoxy or heresy. The term is used in the East to identify those churches (not united with Rome) which accepted the ancient councils, notably Ephesus and Chalcedon, and which call themselves “the holy, orthodox, catholic, Eastern Church.” In the West the word is sometimes used to describe a justifiable concern for sound doctrine in the Catholic faith. (Etym. Greek orthos, right + doksa, opinion: orthodoksa, having the right opinion.)”
Catholic Encyclopedia
The technical name for the body of Christians who use the Byzantine Rite in various languages and are in union with the Patriarch of Constantinople but in schism with the Pope of Rome. The epithet Orthodox (orthodoxos), meaning “right believer”, is, naturally, claimed by people of every religion. It is almost exactly a Greek form of the official title of the chief enemies of the Greeks, i.e. the Moslems (mu’min, fidelis). The Monophysite Armenians called themselves ughapar, meaning exactly the same thing.
How “Orthodox” became the proper name of the Eastern Church it is difficult to say. It was used at first, long before the schism of Photius, especially in the East, not with any idea of opposition against the West, but rather as the antithesis to the Easternheretics — Nestorians and Monophysites. Gradually, although of course, both East and West always claimed both names, “Catholic” became the most common name for the original Church in the West, “Orthodox” in the East.
It would be very difficult to find the right name for this Church. “Eastern” is too vague, the Nestorians and Monophysites are Eastern Churches; “Schismatic” has the same disadvantage. “Greek” is really the least expressive of all. The Greek Church is only one, and a very small one, of the sixteen Churches that make up this vast communion. The millions of Russians, Bulgars, Rumanians, Arabs, and so on who belong to it are Greek in no sense at all. According to their common custom one may add the word “Eastern” to the title and speak of the Orthodox Eastern Church (he orthodoxos anatolike ekklesia).
