Hi,

Here is the end of a characteristic Appalachian version by Knott County ballad singer Hilliard Smith, 1910, from an Olive Dame Campbell MS:

12 The ship setting[sitting] ready
All on sea side
He swore by maker
He'd sail on the other side.

13. All on whilst he was sailing
The ship she sprang a leak
And away to bottom
Sweet William he sank.

14. There he met with Pretty Polly
All in the goes of blood
In her lily white arms
An infant of mine.

15. Such screaming and hallowing
It all passed away,
A debt to the devil
He surely had to pay.
