Seeking info Andrew O. Moe 183?-1921

Andrew O. Moe served two terms. First in the Wis 15th co C and E. Then as a substitute in Wis 7th Co G. I've tracked him first thru the 1890 Vet Sched (in Hayfield, Dodge, MN) and then the Civil War Pension Record (died 1921 in North Dakota) Both these sources list what Regiment and company they were in so sure it's the guy I'm interested in) I have not been able to locate him in 1860 o 1870 census or a marriage record. Or get back to Norway. One civil war record has an alias for him as Ambrea and the 1885 Minn census seems to have Andrias. The 1900 census indicate his marriage was abt 1869 and likely Wisconsin. According to later census he only had one marriage. Census also indicated he came to US around 1853-1854. The Norwegians in the Civil war Vesterheim did have a paragraph on him also. Any additional information would be appreciated.
