Lyrics:

Yn Nyffryn Llwyn Onn draw mi welais hardd feinwen
A minnau'n hamddena 'rol byw ar y don;
Gwyn ewyn y lli oedd ei gwisg, a disgleirwen
A'r glasfor oedd llygaid Gwen harddaf Llwyn Onn.

A ninnau'n rhodiana drwy'r lonydd i'r banna,
Sibrydem i'n gilydd gyfrinach byd serch;
A phan ddaeth hi'n adeg ffarwelio a'r wiwdeg,
Roedd tannau fy nghalon yng ngofal y ferch.

[Down yonder green valley where streamlets meander
When twighlight is fading I pensively rove;
Or at the bright moontide in solitude wander,
Amid the dark shades of the lonely Ash Grove;
'Twas there, while the blackbird was cheerfully singing,
I first met that dear one the joy of my heart

Around us for gladness the bluebells were ringing,
Ah, then little thought I how soon we should part.
Cyn dychwel i borthladd wynebwn y tonnau,
Ond hyfryd yw'r hafan 'rol dicter y don;
Bydd melys anghofio her greulon y creigiau
Un felly o'wn innau 'rol cyrraedd Llwyn Onn.

A thawel mordwyo wnaf mwyach a Gwenno
Yn llong fach ein bwthyn a hi wrth y llyw;
A hon fydd yr hafan ddiogel a chryno
I'r morwr a'i Wenno tra byddwn ni byw.

[Still glows the bright sunshine o'er valley and mountain,
Still warbles the blackbird its note from the tree;
Still trembles the moonbeam on streamlet and fountain,
But what are the beauties of Nature to me?

With sorrow, deep sorrow, my bosom is laden,
All day I go mourning in search of my love!
Ye echoes! oh tell me, where is the sweet maiden?
She sleeps 'neath the green turf down by the Ash Grove.
