Eisten Andreassen Viklem abt 1800 Dverberg

Trying to locate info on Eisten/Esten. No wife found in files. Tried 1865 census for 1872 Dverberg. Son is Andreas Estensen Dahl, b 1836 in Ørlandet, Strindens Parish, Sør-Trøndelag, Norway I think. Found a marriage record for him and Gjertrud Margrete Arnesdatter that indicated they married in 8 July 1875 in Dverberg.
