Sorry, I hadn't realized I could cut and paste. That is I think the poem in question from

Song.
(Welsh Air.—Merch Megan.)

The daughter of Megan so lovely and blooming
I met in Glanavon's gay glittering hall,
And high rose my heart, ambition assuming
To dance with the damsel, the bloom of the ball.
O daughter of Megan, look not so alluring
On a youth that his hope with thy hand must resign,
That now the sad pang of Despair is enduring,
For the splendour thou lov'st can never be mine.

Go, daughter Megan, to circles of splendour,
Each eye that beholds thee thy presence shall bless,
And the delicate mind feel a passion more tender
On thy beauties to gaze than another’s possess.
But, daughter of Megan, to-morrow I’m going
On ocean to sail where the rude billows roar,
And I feel my full heart with affliction o’erflowing,
For perhaps I may gaze on thy beauties no more.
