AMANTIUS of COMO, the third Bishop of Como, St. Amantius was the successor of St. Provinus of Como (8th March). He is credited with the construction of the cathedral in Como, which later bore his name. St. Amantius reposed in 440.

JANUARIUS, MAXIMA, and MACARIA, Martyrs of North Africa, (Date Unknown), listed in ancient martyrologies as having been martyred in North Africa. No further information on their lives is extant.
PERPETUUS of TOURS, the Bishop of Tours (west-central France) from circa 460 until his repose circa 490. St. Perpetuus is remembered for his dedicated care for the poor, to the point of exhausting his own income, and for rebuilding numerous churches in his Diocese.

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 British Saints excerpted from Orthodox Saints of the British Isles.
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.
