Good Book on the history of the Forest of Dean (General)
One good book I've recently read on the Forest of Dean - especially if you're interested in the surname KEAR - is BERMUDA DICK (written by Averil Kear). It's the story of six Forest men transported to Bermuda, after a particularly horrific rape in the Oldcroft, Viney Hill area of the Forest during 1851.
The book (ISBN 1 899889 08 6) is reviewed on this website under Forest of Dean Resources / Books.
I'm also researching the MADDOX families in the forest, and would be interested in your connection.
