Hi Mirla
Like Ocifant i am confused about which routes you sre talking about...do you have details of where they pass through? There are countless variations they could follow but i would guess that the early routes would stick to the high lands as the ground would be drier and visibility of less sociable neighbours would be better
Where did you get the names from?
The Tinners Way is now a popular recreational path and they have a leaflet about it at Penzance TIC if you need to know more.
Will help if I can but need a little more info.
Mr H
