Thank you TFPoP for the information, you've started something now - arrangements are in place to acquire the book.
My original post was in reply to the postcards with comments submitted. I've been a bit naïve, I should have done more research before putting in my two penn'th, still, as they say 'I don't know the meaning of Armageddon - but that's not the end of the world'.
My great-grandfather, William Henry Bosanko left Boscadjack, Sithney and married Eliza Ann Waters from Camborne and then moved to the Hodbarrow Iron Ore mine (25 million tons of the highest grade haematite), Millom, Cumberland in the early 1880's. I don't know which mines he worked at in Cornwall.
droid, nothing too exciting, just another term for a lane.
