Noting what you say above, the two most important words in Welsh that I made sure I knew the meaning of were Dynion and Merched....can you guess which particular public buildings are signed as such?
Concerning loos -- "Gentlemen" and "Ladies" respectively, I believe.
Long ago in North Wales, I kept seeing signpost-like devices which read (at least approx. -- spelling from memory)
Llwybr Cyhoeddus. Found self wondering about this village to which -- rather after the fashion of Rome -- everything seemed to lead. Discovered finally, that it's the Welsh for "public footpath".
Back to quiz matters...
Plumstead in Kent was also once administered by the ancient Hundred of Little and Lessness.
Buried at Plumstead is William Bennet (1746 -- 1820), Anglican Bishop of the diocese of Cloyne in Ireland.
Cloyne, Co. Cork -- some fifteen miles east of Cork city -- is, though a relatively obscure village, the seat of both a Church of Ireland (Anglican) diocese; and a Catholic one.
