I knew that Winifred the mother of the poet Kit Smart was a Radnorian, indeed he boasted of the fact - who wouldn't - in Jubilate Agno: For I am the seed of the Welch Woman and speak the truth from my heart. What I didn't know was that Winifred was the daughter or less likely the grand-daughter of Jeremiah Griffiths of Downton House, New Radnor, which of course is where Innes Ireland lived during his time in Radnorshire.
While wilfing around the matter I also noticed that the novelist Thackery was the great grandson of one Sarah Griffiths of Downton House, the niece of said Winifred. I'm not going to claim Thackery as a Radnorian but Christopher Smart? Certainly.
