Orthodox Saints of the Pre-Schism See of Rome
5th January
CERA (CIAR, CYRA, CIOR, CEARA) of KILKEARY, a native of Tipperary who founded and was abbess of two convents, one at Kilkeary and the other at Tech Telle (Tehelly). There is no further reliable information on this saint extant, and she is sometimes confused with St. Kiara (Chier) (vide infra)
CONVOYON (CONWOÏON) of REDON, an archdeacon of Vannes who became a hermit, and in 831 founded and was first Abbot of the Abbey of Saint-Sauveur, Redon on the border between Neustria and Brittany. St. Convoyon was driven from Saint-Sauveur by invading Vikings and he spent the rest of his life in exile, reposing in 868.
EMILIANA of ROME, (Sixth Century), the youngest of St. Gregory the Dialogist’s (3rd September) three paternal aunts. St. Emiliana and her eldest sister St. Tarsila (24th December), lived as monastics in their parents’ home. St. Gregory wrote of their lives.
GAUDENTIUS of GNESEN, a Bohemian noble and younger brother of Saint Adalbert of Prague (23rd April). He received monastic tonsure at the Abbey of Saint Alessio, Aventine, in Rome, and later joined his brother on his mission to Prussia. Having escaped the massacre in which St. Adalbert was martyred, St. Gaudentius was consecrated the first Archbishop of Gniezno (Gnesen) (in present-day Poland) when the See was established in 1000. St. Gaudentius reposed circa 1004.
KIARA (CHIER) of KILCHREA, a spiritual daughter of St. Fintan Munnu (21st October), she lived in North Tipperary at a place now named Kilkeary in her honour. St. Kiara reposed circa 680; there is no further information extant.
TELESPHORUS (POPE of ROME), a Greek, likely from Calabria, who served as the eighth Pope of Rome. There are varying dates of his reign some sources claim his elevation was as early as 125 others as late as 146, with his martyrdom taking place anytime from 136 to 154. According to the Annuario Pontificio his Pontificate commenced in 127 or 128, and he was martyred 137 or 138. There are many legends regarding St. Telesphorus, though, aside from being martyred, none can be substantiated.
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.
