Claudius, Lupercus, Victorius
Saints Claudius, Lupercus (Lupercio), and Victori(c)us (d. c. 300) are said to have been the sons of St Marcellus. They were said to have been martyred at León, Spain, during the reign of the Emperor Diocletian. Their relationship to Marcellus is probably apocryphal, though it was accepted in subsequent breviaries and hagiographies as well as the Roman Martyrology, which placed all four saints under October 30. However, it is quite possible that Claudius, Lupercus, and Victorius were soldiers of Spanish origin who were killed at León, as tradition states. Many churches in Spain were dedicated to them, including the ancient Benedictine abbey of San Claudio, in Galicia. The town of San Claudio, near Oviedo, takes its name from this group of martyrs.
Their relics were translated several times in succeeding centuries. King Ferdinand I of Castile transported some of their relics to the church of San Isidoro in León. In 1173, the relics were translated to a new church dedicated to the three martyrs. This church was destroyed in 1834 and the relics were moved to the church of San Marcelo, dedicated to their presumed father. Their feast day is celebrated in Spain and Portugal on October 30.
Victorius or Victoricus should not be confused with the French saint of the same name. Another Lupercus or Luperculus was a bishop of Eauze who was venerated as a martyr, and sometimes identified as an uncle of the Spanish saint Saint Engratia.
