MacNeill، Eoin (1926)، "The Native Place of St. Patrick"، Papers read for the Royal Irish Academy، Dublin: Hodges, Figgis، ص. 118–140. MacNeill argues that the southern coast of Wales offered both numerous slaves and quick access to booty, and as the region was also home to Irish settlers, raiders would have had the contacts to tell them precisely where to go in order to quickly obtain booty and capture slaves. MacNeill also suggests a possible home town based on naming similarities, but allows that the transcription errors in manuscripts make this little more than an educated guess.
