The song is attributed to Sìne NicFhionnlaigh from Tong, Isle of Lewis, in the late 18th century. Despite the desperation expressed in the song, it appears that she did marry fisherman Dòmhnall MacRath from Uig a while afterwards. Verse 9 in the previous message infers that Sìne was pregnant when she composed the song, "my belt is getting higher, Not from a fiddler or a harpist, but from the helmsman of a boat,If you don't come home (correct spelling dhachaigh) it will be a pity for me https://www.bbc.co.uk/alba/oran/people/sine_nicfhionnlaigh/
