how Lugnaquilla got its name!

It is said by locals that "Lugnaquilla" is gotten from "log na coille", meaning "the hollow of the wood". The "hollow" might refer to a place called "Crossrahnyeen hollow", near the "Ow" River, which flows off Lug. This is not unusal as a lot of the placenames of upland areas in South Wicklow are gotten from the surrounding geographical feautres or from local family names! The local people all have different varients of how the mountain got its name but the fact that it is taken from the surrounding geographical features is the most likely answer, i got this suggestion from talking to a local person in the nearby town of Donard Co.Wicklow!! I also got the same explaination from a few other people and did some research on it so it is most likely correct...!!!:):):)
