Early Acadian settlers named it because a keg of molasses washed up on shore.
The early Acadian settlers arrived about 1797 from Chezzetcook, where they had been living since about 1758 after the fall of Louisbourg.
Following the American Revolution, many Loyalists flocked to Nova Scotia, and the Acadian settlers were refused land grants in the Chezzetcook area, so many left that area, traveling down the eastern shore and settling in Molasses Harbour (Port Felix), Charlos Cove and Larry's River.
