Anders Anderssen 1771-1854

[Wade Anderson]

I seek ancestors and more information about Anders Anderssen, whose great-grandson Johan Nygaardsvold was Prime Minister of Norway, 1935-1945. Anders  
was born probably autumn of 1771 in Sweden, married 1809 in Malvik, S?r-Tr?ndelag, Norway to Kirsti Svendsdatter Moen, born 1791 at Moen, Malvik. Anders died 1854 at Haaset-Svian, Malvik, age 82.5. Their children were born 1810-1831 in Malvik: Marit, Jon, Andreas, Sven, Marta, Ole, Hans, Kirsten, Ane. (Bygdebok Malvik: Anders came from Lånke, Nord-Tr?ndelag, but his parents were Swedish; Digitalarkivet: Anders Anders. af St?rdalen kommer fra Sverrig). I do not know parents or siblings of Anders, exactly when or where he was born, etc. Thank you for any help regarding this Swedish-born ancestor of mine.
