For some reason, this family looks familiar - but maybe I've just worked on too many Ole Knutsens.
Ole Knutsen was born 25 Mar 1888, probably in Rennebu, Sør-Trøndelag. He came to America in 1891 +-1 year. In 1900 he was living in Prarie Farm, Barron county, WI, with his step-father, Ole Olsen Eide. Presumably, Ole Olsen's wife, Gertrud, is the mother or Ole Knutsen. Gertrud was born in Norway Dec 1863.
