My grandfather was born in 1867 to unmarried parents in the Hammer kommune, Hordaland. In the 1875 census record, I find him living as a plejebarn -- foster child -- with a farm family in Hammer. Is it likely there was some legal procedure placing him in foster care? If so, could I expect to find some record of this in the Digitalarkivet?
It could be many reasons for beeing a fosterchild. It was the municipalites welfare agency by the law of 1865 which enforced it.
The adoption law came 1917, but it was legal adoption before that.
A child born out of wedloc had no legal right to inherit the father or the fathers family before 1917 if the father did not "Lyse i kull og kjĝnn" claimed paternety, law by 1854. If the father claimed paternety the child could inherit up to 50% of the children born in wedloc.
