Seeking birth and marriage record for Kersti Halvorsdotter born 1808, Idd, Ostfold, Norway; parents Halvor Iversen & Kirstine Larsdotter.
Kersti Halvorsdotter married Olof Johannsson (born in Toftedal, Vastra Gotaland, Sweden 1803). As far as I know they married in Norway. They lived in Norway several years and had 4 children there before moving to Alvsborg - now Vastra Gotaland, Sweden.
I have located the year 1808 on the Idd, Ostfold, Norway Archives site but can't read the writing very well. I know Idd, Ostfold is very near the Swedish border and Sweden's Tresticklan Park.
