All those years I studied Scottish History wasted, I could just have read Wikipedia.
As I have already stated - this is the Lanarkshire Board and I presume the thread here is touching on Woodhall Colliery, something that did not exist in 1605, 1770, 1775 or at anytime before the last Act of Parliament outlawing the servitude of colliers.
The Dukes of Hamilton owned vast swathes of land in Lanarkshire, Stirlingshire, East & West Lothian etc. Carron Iron Works, last time I checked, was where it always was, on the banks of the river Forth, Stirlingshire. That may have been on land owned by the Hamilton family as part of the Kinneil Estate.
Please go back and check the original question on this thread, it only concerns the middle years of the 19th century onwards and has nothing to do with serfs and lifelong servitude.
If this did indeed happen in Lanarkshire (this is the Lanarkshire Board, just to remind people once again) where is the proof, forget about Wikipedia and hearsay, where is the actual written proof and where in this county of Lanarkshire did this happen?
If I can see evidence I'll be happy to hold up my hand and say "I was wrong" but, if, after the dates mentioned at the beginning of this post, there was such a situation in Lanarkshire, I would really like to know where.
No one is disputing what happened centuries ago in other parts of the country but, is it relevant to the original post concerning a family who only arrived in the country in the mid 1850s?
If it isn't relevant then why cloud the issue with it?
