I’ve just been reading the last message from Suds and I had a thought.
The Sudlow name is very similar to Ludlow (in Shropshire) and Ludlow Castle used to belong to Joce de Dynan, with one gate surrounding the moat still called Dynan/Dinan gate.
So I’m just wondering....stretch of the imagination I admit...if ‘Sudlow’ was at some point ‘Ludlow’ but was mis-transcribed or mis-read from Cursive script ‘L’ and ‘S’....maybe!? (Weirdly my gadget keeps trying to turn Sudlow to Ludlow too!).
Apologies if this is a wild goose chase/flight of fiction, but I do know ‘mis-transcription’ errors occur.
