Claim: Quirinus of Neuss was venerated by Catholic and Eastern Orthodox churches with a feast day on the 30th of April.
Evidence: Quirinus of Neuss (German: Quirin, Quirinus), sometimes called Quirinus of Rome (which is the name shared by another martyr) is venerated as a martyr and saint of the Catholic and Eastern Orthodox churches. The Martyrologium Hieronymianum assigns him under the feast day of April 30, the date that appears in the catalogue of Roman martyrs of the 4th century.
