I had not responded when this was first posted as I was home so little and my hymnals were boxed up but was a bit concerned that so few Welsh melodies were reported in Methodist Hymnals. As it is I cannot add much but did find the following in the 1989 Methodist Hymnal. The index only listed five Welsh folk melodies but scanning through the index produced the whole list. In addition, there are three responses by Robert Williams who is credited with the melody, Llanfair.
