" And on the lonely river-marge
She clears his hearth for him."

I've always known it as:

Her father sails a running- barge
Twixt Lambeg and The Drum;             (1)
And by the lonely river's marge
She keeps their humble home.
When she was only fairy-high          (2)
Her gentle mother died;
But still she keeps her memory bright
Down by the Lagan's side.

(1) I quite like the association here: the Drum was a lock on the Lagan navigation, it's also the name of a pub. But there's also the Lambeg drum...

(2) Careful not to sing 'fairly high' or 'very high' here.

I posted the first verse in French here a couple of years ago, it seems to translate quite well. Anyone fancy a go at the rest?
