Wow! Thanks for all the insight Ingvar! It is fascinating to find out how one's ancestors made their living from day to day.
You said that later on Bergsmen became rather wealthy. That would seem to fit as my Great Great Grandfather (f,m,m,f), Johan Andersson Ljung, was a Bergsman in Karlskoga and when his wife passed away in 1913, he was able to erect a very fine monument in her honor in the Karlskoga graveyard. I have a photo of it as it looked in 1913, just after her burial, and a photo of it as it looked last winter, sent to me by a friend in Karlskoga. It still looks almost as it did back then even though it is almost 100 years old!
Also, I just recently found out that on another branch of the family tree that I am descended from Belgian Walloon miners who signed a contract with the King of Sweden in 1625 to mine in Sweden.
One of my ancestors was a Kolare or charcoal-burner. Another article I read about mining techniques in the middle ages said that they used to pile wood in front of rock walls that were to be mined and burned the wood to make the rock brittle so they could break it up with hammers.
Another one of my ancestors was a Hammer Master, so I assume they were involved in using those mining techniques I read about.
Again, I thank you for your insight into Bergsmen and what they do. I am printing your response and adding it to my family research.
Gratefully,
John
