I am not a member of Mudcat but I'm trying to help my wife, Monica, in her efforts to find the words of a song her father had.
Her recollection of the Air would make it very close but not identical to that of "The Bantry Girl's Lament" as sung by Mary Black.
The only lyrics she can remember are as follows ( and they might not be 100% accurate)

Boy you have come of gentle blood
But now of poor degree
Where e're you go may God the good
Smile on your destiny

What e're the future, dark or bright,
In life's ---------- span
When Fortunes glows and darkest night
Still prove yourself a man.

I previously gave Mudcat the lyrics of an old song called Absent (by Metcalfe circa 1890) so you might look favourably on this request for help.
I did not join Mudcat because I was fearful of getting extra mail.

Yours sincerely
