He was a carpenter in the 1880 census when he was located in Winona, MS. My aunt said that they had speculated he may have been a timber man, because she has not been able to find him in any emigration (from Norway) or immigration records to the U.S. She said that a lot of ppl from Norway came through Canada, because it was cheaper, and I noticed myself there sure was a lot of Dahl's up north. She said there was a lot of timber in Mississippi at the time, and he probably migrated to the area for work. I'm not sure how all of it is known, because my aunt has been doing the legwork for our family genealogy long before the internet, but she says he was born in Christiania, Norway, as was his oldest son Albert Olsen, and she insists his middle name was spelled like that, and not the other spelling that is primarily being used, Olson. She told me Norwegian naming patterns were different than they are here, and that at the time in 1871, Norway was actually a part of Sweden, thus in some of the records - many of them in fact, say they are from Sweden. I've read up on all this, and of course what she says lines up with what I'm reading. I've learned just a very little about the naming, like the -sen endings, or what have you, but I'm still a long way from really understanding them.
