Many thanks dobfarm and Ruskie! Sorry for the delay in replying but I have been away on holiday for a couple of weeks. Your information, pinpoints where Workhouse Hill was/is.
Dobfarm, I would be interested to know where you obtained the map you posted. I have scoured the NLS site which, as you probably know, has an extensive offering of old maps, but I could not find Workhouse Hill on any.
Thanks to both once again for your invaluable help.
