I am trying to find a naturalization record or passenger list for these people. I know Charley j. Swanson was born September 1860 in Sweden. Amanda was born November 1860 in Sweden. They came over to the U.S. in 1881. They also had a kid with them named Lottie Swanson. In the 1900 census, they are in Galesburg Ward 4, Knox, Illinois. If you guys could help me find any immigration records on them, that would be great!
