I am looking for the author/source for an old folk song.
My dear departed Aunt used to sing a song that we called:

Cape Breton Farewell

Chorus:
These are the last hours I'll spend in Cape Breton
Please God arrange it so I'll see once more
My own lovely land at the dawning of morning
And then be returning to Cape Breton's fair shore

At the dawn of the morning my ship will be sailing
To take me away from the land of my birth
And I know in the morning my heart will be breaking
For I'm leaving the place i hold dearest on earth

I have more verses but woul like to find the songwriter/originator.
