Orthodox Saints of the Pre-Schism See of Rome
4th September
BONIFACE I, forty-second Pope of Rome from 28th December 418 until his repose 4th September 422. There is little in the way of reliable information on his life prior to his election. According to the Liber Pontificalis St. Boniface was a Roman and the son of a priest by the name of Jocundus. He is thought to have been ordained by Pope St. Damasus I (11th December) and may have served in the early fifth century as representative of Pope St. Innocent I (28th July) at Constantinople.
CALETRICUS of CHARTRES, the successor circa 557 of St. Leobinus of Chartres (15th September) as Bishop of Chartres (north-central France). St. Caletricus reposed circa 580, and nothing else certain is known of his life.
CANDIDA the ELDER, an elderly woman in Naples who embraced Christ after being miraculously healed by the Apostle Peter (29th June). She later brought St. Aspren of Naples (3rd August) to Christ, and later St. Aspren became the first Bishop of Naples (southern Italy). St. Candida reposed circa 78.
IDA of HERZFELD, a young widow who founded Herzfeld Abbey in Westphalia (north-western Germany), devoting the rest of her life to good works. St. Ida reposed circa 825.
MARCELLUS (MARCEAU) of CHÂLON-SUR-SAÔNE, a priest in Lyons (east-central France), who was arrested in the persecution of Christians during the reign of Emperor Marcus Aurelius (r.161–180). St. Marcellus escaped from prison, and continued to preach the Gospel. Unfortunately, he was arrested again, and tortured before he was buried up to his waist on the banks of the Saône (eastern France) and left to die. St. Marcellus survived for three days before he reposed circa 178.
MARCELLUS of TREVES, (Date Unknown), little to nothing reliable is known about this saint. However, both Tongres (Belgium) and Treves (present-day Trier in south-western Germany). have claimed him as having served as one of their early bishops.
RHUDDLAD, (Seventh Century ?), St. Rhuddlad is the patron saint of Llanrhyddlad (Welsh: Llan-Rhûddlad) in Anglesey, Wales. There is no further information on her life extant.
SALVINUS of VERDUN, there is no information on this saint extant, beyond that he was the successor of St. Maurus of Verdun (8th November) as the third Bishop of Verdun (north-eastern France) and reposed circa 420.
SULPICIUS (SULPICE) of BAYEUX, twenty-first Bishop of Bayeux (north-western France) from circa 838 until he was martyred circa 843 by Vikings in Livry, Normandy (northern France).
ULTÁN MOCCU CHONCHOBAIR (ULTAN of ARDBRACCAN), St. Ultán was the Abbot-Bishop of Ardbraccan, Co. Meath, Ireland. Although no contemporary Lives have survived, the Annals of Ulster record the year of his repose as 657, and extensive mention of him is made in the Félire Óengusso (Martyrology of Ængus). He is remembered for his care of the poor, and especially his work on behalf of destitute and orphaned children.
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.
