Indeed, Tootler; & thank you. You have clarified the matter admirably, and we are obviously dealing with two different sequences of events in different versions of the song.

Some versions, esp I think the on-board ones in my consciousness, say that "from Liverpool she came. For 14 years transported for playing of the game"; which adds force, I think, to my point that the ship's captain was asking for trouble in marrying her quite so 'out of hand', & the 'good usage' she 'gave us all' for the remainder of the voyage was no more than he should have expected!
