The Celtic Scholar Charles Plummer suggested that Piran might, instead, be identified with Ciarán of Clonmacnoise, who founded the monastery of Clonmacnoise also in County Offaly, but this is doubtful since this saint is believed to have died of yellow fever at the age of thirty-two and was buried at Clonmacnoise. His father is, however, sometimes said to have been a Cornishman. David Nash Ford accepts the Ciarán of Clonmacnoise identification, whilst further suggesting that Piran's father in the Exeter life, Domuel, be identified with Dywel fab Erbin, a fifth-century prince of Dumnonia (Devon and Cornwall).
