Orthodox Saints of the Pre-Schism See of Rome
30th April
AMATOR, PETER, and LOUIS, St. Amator, a priest; St. Peter, a monk; and St. Louis, a layman; who were martyred in 855 by Moors in Córdoba for encouraging their fellow-Christians to keep the Faith no matter how severe the tortures they faced were.
CYNWL, (Sixth Century), St. Cynwl was the brother of St. Deiniol (11th September), the first Bishop of Bangor, Wales, and lived an ascetic life in northern Wales. After his repose several churches were dedicated in his honour.
EARCONWALD (ERCONWALD, ERKENWALD) of LONDON, (Seventh Century), an East Anglian Prince who renounced the world and used his fortune to build two monasteries, one at Barking, which he placed under the direction of his sister St. Ethelburgh (11th October), and the other at Chertsey where he served as the first Abbot. In 675 St. Theodore of Canterbury (19th September) consecrated him Bishop of London. Governing that See for the remaining eleven years of his life, St. Erconwald proved to be an able and pious prelate. He reposed in 686 and his tomb in Old St. Paul’s became a centre of veneration, famous for miracles.
EUTROPIUS of SAINTES, consecrated a bishop and sent to evangelise the area of Aquitaine centred around Saintes (present-day France). St. Eutropius served as the first Bishop of Saintes, and is said to have been martyred circa 250. Many sources state he was consecrated by Pope St. Clement I (23rd November) who reposed in either 99 or 101. He is also said to have been a companion of St. Dionysius of Paris (9th October) who reposed in either 250, 258, or 270. Obviously as there is over a century between the dates St. Clement and St. Dionysius flourished, both theories cannot be correct.
FORANNAN, an Irish monk, and later Bishop of either Domhnach-Mór (Donaghmore), Co. Wicklow or Armagh, Co. Armagh, Ireland. St. Forannan left Ireland settling at Waulsort (present-day Hastière, Namur, Belgium). There he either joined the newly founded, or was one of the founders of, Waulsort Abbey (abbaye de Waulsort). In 962, St. Forannan became Abbot of Waulsort. He reposed in 982.
JAMES, MARIANUS, and COMPANIONS, St. James, a Deacon; St. Marianus, a Reader; along with a group numbering in the hundreds, were martyred in 259, at Cirta in Numidia (present-day Constantine, Algeria), during the Valerian persecutions.
LAURENCE of NOVARA and COMPANIONS, a friend and assistant of St. Gaudentius (22nd January), Bishop of Novara, in Piedmont (north-west Italy). St. Laurence was martyred circa 397, along with a group of children he was catechising.
POMPONIUS of NAPLES, consecrated the twenty-second Bishop of Naples (Italy) in 508, serving until his repose in 536. St. Pomponius ardent defender of orthodoxy against Arianism.
SOPHIA of FERMO, a maiden in Fermo in present-day Italy, martyred circa 250 during the Decian Persecution.
SWITHBERT the YOUNGER, originally from England, St. Swithbert went to Germany where he is believed to have spent time working with English missionaries. Later he was consecrated Bishop of Werden in Westphalia (present-day Germany). St. Swithbert reposed in 807.
Prior to the Schism the Patriarchate of Rome was Orthodox, and fully in communion with the Orthodox Church. As Saint John of Shanghai and San Francisco +1966 said “The West was Orthodox for a thousand years, and her venerable Liturgy is far older than any of her heresies”.

Details of continental saints from these sources.
In many cases there are several spelling versions of the names of saints from the British Isles. I use the Oxford Dictionary of National Biography version as the primary version with the more prevalent version in parenthesis e.g. Ceadda (Chad) of Lichfield.
