"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. His cult was centered at Neuss in Germany, though he was a Roman martyr.
According to the Catholic Encyclopedia, a Roman martyr named Quirinus was buried in the Catacomb of Prætextatus on the Via Appia. The Martyrologium Hieronymianum (ed. De Rossi-Duchesne, 52) mentions Quirinus' name and place of burial. The Itineraries to the graves of the Roman martyrs (Giovanni Battista De Rossi, "Roma sotterranea", I, 180-1) also mention these two pieces of information." - (en.wikipedia.org 22.04.2021)
