Hi, we have a Carl August Johnson in our family. I dont know if this is the same one but he died in 1903 in clintonville wisconsin. He had 2 brothers John and Gust who lived in the Breed area of Oconto County for quite some time. They all came from Sweden during the 1880s. Gust was my great great grandfather. Your timeline is very similar to my familys. I do not know much about Carl. But John and Gust never moved to Russia and Gust was a laborer and John was involved in a general store. Dont know if this is relevant to you, but it may be a lead for you.
