Benjamin...did you leave someone out!?
Haha. Well, there are actually more. They're pretty small, though. The only one I would've considered of note that Michał mentioned is the Ukrainian Autocephalous Orthodox Church Canonical
(UAOC-C), which distinguishes itself from the UAOC I mentioned above, and claims it has independence from the Polish Orthodox Church. It is in fact not
canonical. It is lead by Patriarch Moses
As for Archbishop Igor, he once was connected to the UAOC, but split and is, as far as I know, on his own...episcopally speaking. You can get information about him from this thread
Both of these are pretty teeny-tiny, for the record.
HEAD SPIN ALERT: I don't think that the UOCC was ever a 'branch of the UGCC (i.e. Ukrainian Greek Catholic Church). It was established in 1913 as an independent Orthodox body. Just like the OCA and ACROD, its establishment may have been a result of turmoil and dissent within the Greek Catholic church but you can't say that any of these groups were ever 'branches' of Greek Catholicism. There are parishes in each which originated as Greek Catholic congregations, my own in Binghamton, NY is in that group, but the parent jurisdiction was established as an Orthodox Christian body. We don't need to discuss the canonical status of the UOC-USA and UOC-Canada pre-1990 except to say that both were Orthodox.
I stand corrected. The UOCC's history is rather confusing for me as well. After a little more reading, I can say that it was founded by Ukrainian immigrants that were both Orthodox and Catholic, and were known as the UGOCC. They're canonicity bounced back and forth, as they had primates that were canonical (such as Met. Germanos of the Antiochian Orthodox Archdiocese) and ones that were not (such as Met. Illarion of the UAOC). However, they have been stable since 1990, when they were brought under the omophor of the Ecumenical Patriarchate. This is a history they share with the Ukrainian Orthodox Church in the USA.
