Dwynwen goes on to establish many Christian churches, along with her sister Cain and her brother Dyfnan. Dwynwen's own church is off Anglesey, Llanddwyn, the remains of the church are still there and people still travel to it to pray to Dwynwen to help them with their love.
The Englyn is a short Welsh and Cornish poetic form, similar to that of the Haiku.
Maelon, in your heart, do you still shiver,
from prayers icy dart
the angel of the river,
Brychan Brycheiniog's temper?
Maybe you dream, with me, at Llanddwyn,
a swollen memory
Angelsey, or an omen
of what we should have known, then.
But now you have gone, with Dyfnan and Cain,
and our sublime bygone,
to another place and time.
Here. I, mother to love's crime.
