Looking for info on my 3rd Great Grandfather

Hi, I'm researching my 3rd Great grandfather Martin Stenerson He was born around 1854 and immigrated from Norway in 1886 . He changed his name totally. His last name was Andersen. He showed up in the 1900 census in Wisconsin. See I can't find him at all before 1900 in the United States . I believe his name was Martinius Andersen, but I can't prove it . if that is his correct name his parents are Anders Stenersen and Susanne Erkisen. I'm looking for any information that might help me . I'm thankful for anything. Thank you so much for your time. Talony[:)]
