Thank you all...I have tried the two links shared, nothing found...
names: ggrandfather- Mathias Christopherson Mortensen born October 10, bapitized November 14,1838, Bergen (his parents Christian Mortensen and Karen Marie Knutsen no dates for them). Great grandmother- Alberthine Gothilde Knoph-born January 8, 1839 in Trondheim. Mathias and Alberthine were married in March 19, 1865 in Domkirken (name of Church) Bergen. I am also looking for a paying service to do this search, I would be willing to use them as I did with the Norwegian Emigration Center when looking for my grandparents information...my great grandparents never left Norway only two of the of their chidlren. GG/parents are on the 1875 Bergen census. Thank you.
