The term Corcu Duibne has survived in the name of the Dingle Peninsula.
According to Bourke, Hayden, and Lynch, "No evidence for this association with Fionán has thus far been identified in early medieval texts...Skellig Michael is not recorded as one of the sites founded by Fionán, which is a curious omission, given the likely proposed regional significance of the site (Ó Carragáin). 2008).The earliest identified instance of the association is the assertion by Smith (1756, 61) in his account of the site that it was originally founded by Fionán. Subsequent scholarly work on the site derives the association with Fionán from Smith's account." (Bourke, Edward, Alan R. Hayden, Ann Lynch. Skellig Michael, Co.

The early Irish church had two different St. Fionáns: Saint Finian the Leper, and St. Finnian of Clonard.
