I'm not sure I could advise where to get a copy of 'The spirit speaks loud' - I was lent a copy by a wensleydale local connected to the Aldersons.The book covers all(?) the main surnames in Swaledale from incredibly early (c13?).It's a really hard book to read - no index, a bit repetitive, and very complicated (as I'm sure you can understand if you are researching any surnames in Swaledale!).
I'll have another look at the borrowed copy, and try and get you more info about it (try amazon?) although I think it might just have been produced locally!What are your Swaledale interests?
