Pope Alexander I was the bishop of Rome from c. 107 until his death c. 115. The Holy See's Annuario Pontificio (2012) identifies him as a Roman who served from 108 or 109 to 116 or 119. Some believe he suffered martyrdom under the Roman emperor Trajan or Hadrian.

Quirinus of Neuss, sometimes called Quirinus of Rome is venerated as a martyr and saint of the Catholic and Eastern Orthodox churches. His cult was centred at Neuss in Germany, though he was a Roman martyr.
