Sorry but nothing to do,with your query, but what is "heddwych",I ask because when my second son was very small he would draw fantastic pictures,we never said "what is it "because he would get so frustrated
that we did not know, so we always asked him to"tell us all about it ".
Invariably there would be at least one hedwidge-- we did not have a spelling of course but it sounded like that.
There used to be a children's programme "Pobol y cwym".That may be wrong but it is 54 years or more ago. Although we were not in Wales we could get it on Granada or BBC.
He never could say what it meant to hiim so we never found out.
Whatever it was to him will of course not be what heddwych really means .,
Just curious,but whatever it was there were at least two of them at his depiction of The Battle of Hastings done when he was nearly six but he had drawn them for a couple of years before that.They were just matchstalky figures,nothing much to make them differ from other characters in his drawings.
Cheerio. Viktoria.
