My grandparents,HALVOR KNUDTSON and LISA JACOBSON,lived in Blair, Trempealeau Co. I know about them, but I'm looking for families of siblings. HALVOR JACOBSON came to WI from Grue, Hedmark, before 1883. He lived in the Blair area. KNUT, ANDREW, and MARI Knudtson came to the Blair area in mid-1880's. Mari married (?) in Blair. I would like to find their families. Thanks.
