What is recorded here

Dernish Island off Sligo may have been the true Fomorian stronghold rather than Tory Island, its name a corruption of Tor Inis and its tidal waters matching legend. A tower ruin stood on its high point until a farmer reused the stones around 1880, while Milk Harbour opposite still bears the memory of daily tribute. What is fact is thin, but the shape is clear: a small island doing heavy work in the imagination, taking children and milk and leaving behind a name.

Dernish Island is recorded as a island in County Sligo. Its open map record supplies this location and any linked names or public references.
