1801 Census - what two expression mean

I'm trying to locate my 4x great grandfather. We know my 3x great grand mother was Maren Johnsdatter and was born March 16, 1822. We been told it was in Upper Telemarken. We have her name in 1) Aase Marie Birth Record 1847 (my 2X) was born in Søndeled, Aust-Agder 2) Ingeborg Johanne birth record 1848 3) Emmigration records 1850. Two of Maren's sons stated that Maren's maiden name was Torgerson and their grandfather was John Torgerson. These boys were born in Wisconsin. In searching the 1801 census for John Torgersen, I've come across two expression that I was hoping someone could translate. 1) 1 1ste ægteskab 2) Konens ægte- og huusbondens stifbørn
