I'm looking for Lars Pedersen and his wife Berte Olsdr. They had 3 children christened in Lier, Buskerud, between 1811 and 1817. Searching backward from 1811 to 1800, I am unable to find any more children or a marriage record. Since none of the children is named Peder or Ole, I'm assuming there are at least 2 older sons.
Unfortunately, the bygdebok for Lier is VERY sketchy; the record of this family ended several generations before this.
Any suggestions where else to look?
