might I suggest purchase of a map - the public rights of way is 1:25000 and available for less than £10 via Museum shop - I also understand that the 6in/mile pre 1900 O/S maps are free online and I think accessible via Google - MNB has placenames - the MNB CD rom also has the original 1"/mile O/S map of 1868/9 (a reprint of which is also on sale at Manx Museum shop)
