6th century. Only their names and place names honouring these Welsh
saints remains of their history, and the fact that they were given a
public veneration in Wales. Saint Brothen is the patron of Llanbrothen
in Merionethshire. Dolwyddelen and Llanwyddelan in Montgomeryshire
suggest a Saint Gwendolen; this and similar names are diminutives of
Gwen (meaning 'white'), equivalent to the French Blanche (Benedictines).

As in your native Wales you won souls for Christ by your witness,/O
Righteous Brothen and Gwendolen,/ so now in heaven intercede for us/
that our souls may be saved.
