"Carrickfergus" is an Irish folk song, named after the
town of Carrickfergus in County Antrim, Northern
Ireland. The origins of the song are unclear, but it
has been traced to an Irish language song, "Do bhí bean
uasal" ("There Was a Noblewoman"), which is attested to
the poet Cathal Buí Mac Giolla Ghunna, who died in 1745
in County Clare.
The song appears on a ballad sheet in Cork City in the
mid Nineteenth Century in macaronic form.
