Hi! The sitewww.digitalarkivet.nois a great place when trying to find Norwegian ancestors (also when you're an English speaker).
If you look there, the only Hans Hoff born 1862 mentioned is Hans Kristian Johansen Hoff. He, however, married Elen Marie Nilsdatter - so may be it's the wrong Hans Hoff anyway?
I myself know that I have/have had Hoff relatives in Wisconsin (probably also Minnesota). When my grandfather's brother Engebret went to the U.S. in 1900, he went to Wisconsin, as he already had uncles - more than one, that is - living there. Engebret and his relatives hailed from Kongsberg, Norway - and/or Rollag/Veggli, or Numedal. Anybody who knows more? Are there preserved Wisconsin records from, say, 1850-1900?
