Yes Roger, I consider myself pretty handy with a search engine & also spent a lot of time searching the web re this enquiry but to no luck wrt the Forest specifically. However he was clearly a photographer of flora & fauna so its not unreasonable to think he'd have travelled the Forest & Wye Valley area too ?.
What I found amusing is that he's world famous by a name that is not entirely correct and that he himself didnt like !. Ah well, the price of fame !

ps Roger, are you by any chance related to a heroic player of a certain local football team who I have a high regard for, namely the Lilywhites of Hereford ?
