The song looks like it is a variant of "The Indian Lass" or "Little Mohee", which are found on both sides of the Atlantic, with the notable difference that the Creole girl refuses the propositions of the wanderer (a sailor in Indian Lass). My favorite version of The Indian Lass was done by Nic Jones on "The Noah's Ark Trap". I like Paul Brady's version of LoP a whole bunch; Martin Simpson's recorded it to a Cajun beat (not entirely successful, IMHO)
