I am making this post as it is somewhat related to Orthodox history:
Earlier today I was talking with our Subdeacon Tikhon and he mentioned coming across this group calling itself the "Ancient Church of the West" on Facebook/YouTube, the link provided: https://ancientchurchofthewest.com/
They claim to be Orthodox and do a "Western Rite" and on their website mention having come from the Patriarchate of Alexandria, which more than likely means they are from the lineage of Arnold Matthew (sometimes spelled "Matthews"), who was an Old Catholic bishop cited as a founder for several episcopus vagante groups that exist today.

The topic that's relevant to the history of Orthodoxy are the following, cited from the Wikipedia page "Western Rite Orthodoxy" (https://en.wikipedia.org/wiki/Western_R ... th_century)
"Some speculate Bishop Mathew's 1909 Old Catholic Missal and Ritual may have been approved as a Western Rite liturgy by Pope Photios of Alexandria. Both unions were contracted in quick succession and only lasted for an effective period of a few months. Though the union was protested by the Archbishop of Canterbury to Photios and the Patriarch of Antioch, Mathew's group claimed that communion was never formally broken off."
And from the Wikipedia page on Arnold Matthew: "Now an archbishop, Mathew was in contact with people interested in expanding the Eastern Orthodox Church's presence in Western Europe. Olga Novikov, along with Baroness Natalie Uxkull-Gyllenband, encouraged and financially assisted Mathew and according to Anson, one of them also introduced Mathew to Greek Orthodox Church of Antioch Archbishop Gerassimos Messara, Metropolitan of Beirut.
Moss wrote that Messara 'had no power to do this without the consent of' Gregory IV, in Damascus, 'which was never given'. According to Herzog, Gregory IV retracted Messara's statement. 'It is hard to believe that an Orthodox Patriarch of Antioch would have been prepared to accept a married prelate into communion with his Church,' Anson wrote. Mathew's wife 'did not take part in the conference, and it is probable that her existence behind the scenes was again kept dark, as at the time of her husband's consecration in 1908.' On 26 February 1912, Greek Orthodox Church of Alexandria Patriarch Photius of Alexandria, allegedly also accepted this union. The Mathew v. 'The Times' Publishing Co., Ltd. trial revealed that although Mathew 'was originally informed that all were welcome, he was not ultimately admitted' as a cleric into the Greek Orthodox Church of Antioch."
I'm not sure why Olga Novikova supported Arnold Matthew, or how many groups claiming to be descended from him actually exist (and among those who even claim to be Orthodox) but he is definitely one of the most infamous vagantes of the 20th century along with Aftimios Ofiesh and Martin Ngo Thuc.
