This is the note we did for the double CD, Around the Hills of Clare
It's been challenged, but it still makes some sort of sense to me.

"The title Maid of the Moorlough Shore at first suggests the location as being Murlough Bay, north Antrim, but it has also been found as Maid of Mourne Shore which places it further south. This might explain Martin's reference to the River Shann, as an outlet to Lough Shannagh flows through Silent Valley from the Mourne Mountains, emerging out to the sea at Kilkeel, South Down.
Hugh Shields links it to this latter area with a local story of a miller's daughter betrothed to a fisherman, the marriage fixed to take place on the eve of Greencastle Fair. Her lover is drowned in a storm and the girl, finding the body, loses her mind and is herself drowned."
