I'm so glad there are so many people interested in the song "The Isle of Innisfree". I have listened to this song by Danniel O'Donnell as well as Sinead Stone on the CD "Legacy of a Quiet Man." In each case they pronounce Innisfree as (Inn-ish-free). Apparently this is correct, however, I'm not sure where they get the (ish). The title has nothing to do the "The Lake Isle Of Innisfree", but rather the song is about Ireland. Dick Farrelly used the name Innisfree to refer to Ireland.
