if you search on the census for men living in Cornwall in mining areas with Scotland as their place of birth, there are a few who show up.
So in 1851 there is a John Marks born Scotland aged 49 in Camborne who is a sexton HO107/1916 folio 20 pg 33. When he married in 1841 as a widower, he and his father were both miners.
Also in 1851 in Camborne there's a mine agent George Swan born Scotland HO107/1916 folio 45 pg 6
And in Kenwyn in 1851 there's a John Yellow (corrected to Yelland) aged 27 copper miner born Scotland.
