My grandfather was a miner iin Canton. According to my Mother one of his jobs was to set the charges on Sunday so the air would be clear in the morning. I believe g-grandfather would have been a miner also. He came to the USA around 1870 and married in Fulton County where he settled and raised a family. I know that g=g'pa had some brothers who came from Sweden also. Can you be a little more specific about your Swanson connection.
