Sewinbasher - that would be nice as I never saw that publication.
Spy1 (now Gwilym on this forum) wrote fondly of the Dwyfawr in his autobiography:
The Angle of the Cast
He grew up there, so he, mostly, spells
Dwyfawr correctly.
Then south Caernarvonshire, long time constituency of Liberal Prime Minister David Lloyd-George, in recent times re-named
Dwyfor (two-seas): quite logical as the region encompases the Lleyn peninsula. Dwyfor County Council mistakenly put up
Dwyfor signs on the road bridges thus perpetuating the (now escallating) error. True locals - few and far between in this region now very much geared to the tourist industry.
My family owned land in the area, we still have bankside land in Dolbenmaen and upper reaches Cwm-Pennant. The deeds and boundary maps clearly state
Dwyfawr.
