Orthodox Saints of the Pre-Schism See of Rome
27th October
ABBÁN of MAGH-ARMUIDHE, (Sixth Century), the nephew of St. Kevin of Glendalough (3rd June) and the founder of many monasteries. He is often confused with St. Abbán of Kill-Abban (16th March) who was the nephew of St. Ibar of Meath (23rd April) and founder of Kill-Abban monastery in Leinster, Ireland. Unfortunately, there is no reliable Life of either of these saints extant.
Troparion of St. Abbán of Magh-Armuidhe — Tone VIII
In Ireland's fertile soil thou didst plant the seeds of
monasticism, O Father Abbán,/ and didst nurture
a great flowering of God-pleasing virtue./ Continue
steadfastly in thy enduring love, to lead mankind to
God/ and by thy prayers may we be granted great mercy.
COLMÁN of SENBOTH-FOLA, little is known of St. Colmán. He was Abbot of Senboth-Fola near Ferns in Ireland and is believed to have been a disciple of St. Áedán of Ferns (31st January). St. Colmán reposed circa 632.
Troparion of St. Colmán of Senboth-Fola — Tone VIII
Through trials and temptations thou didst shepherd/
steadfastly in thy enduring love, to lead mankind to
the monastics of Senboth-Fola, O Father Colmán,/
steadfastly in thy enduring love, to lead mankind to
and didst guide many souls on their pilgrimage to Christ./
Wherefore, we pray thee, intercede with Him,
that our souls may be saved.
DESIDERIUS (DIDIER) of AUXERRE, consecrated the twentieth Bishop of Auxerre in Burgundy (east-central France) in 614, St. Desiderius served the See until his repose in 625.
FLORENTIUS of TROIS-CHÂTEAUX, a third century martyr in Trois-Châteaux in Burgundy (east-central France). No further information on his life is extant.
GAUDIOSUS the AFRICAN (GAUDIOSUS of NAPLES), amongst the many orthodox Christians forced into exile by the Arian Gaiseric, King of the Vandals (r. 428–477), was St. Gaudiosus, Bishop of Abitina in Africa Proconsularis. Exiled in 440, St. Gaudiosus settled in Naples where he founded a monastery and lived until his repose circa 455.
NAMATIUS (NAMACE) of CLERMONT, the ninth Bishop of Clermont (central France), serving from circa 446 until his repose circa 462. His episcopacy is principally remembered for the building of the Cathedral of SS. Vitalis and Agricola. In History of the Franks (II.xvi), St. Gregory of Tours (17th November) wrote a detailed summary of the completed cathedral of which he says "the fear of God is in it".
ODHRAN (ODRAN, ÓRAN, OTTERAN) of WATERFORD, St. Odhran has always been held in great veneration in Ireland. He was an abbot in Co. Meath, Ireland, accompanied St. Columba of Iona (9th June) to Scotland, and is said to have been the first person to repose at Iona (circa 563). The graveyard at Iona is called Reilig Odhráin (St. Odhran’s Graveyard) in his memory. According to Irish tradition, St. Columba saw devils and angels fight over St. Odhran’s soul before it ascended into heaven. St. Odhran is also the main patron saint of the Diocese of Waterford, Ireland.
Troparion of St. Odhran of Waterford — Tone VIII
O Father Odhran, thou wast the first among the
saintly Columba's disciples to repose/ and be laid to
rest in the blessed soil of Iona./ As in thy life thou
didst live only for Christ,/ we pray thee to intercede
for us that we may follow thee into the way of salvation.
VINCENT, SABINA, and CHRISTETA, Martyrs of Avila, three Spanish Christians, and siblings, who were martyred during the Diocletianic Persecution (303–313).
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.
