If it is phonetic (which is highly likely) and if lagunasf is looking to the West (a bit adrift from Galway, I admit), then could we be in places like Collooney (Irish: Cúil Mhuine) and Coolaney (Cúil Aine) in Sligo?
Killarney (see above) would also be Cill Airne, but then there are dozens of place-names with "Cill" (=church) anglicised to "Kill-" or "Kil-"
