Halvorsens in Eau Claire

I have earlier asked for help here looking for Theodore Wicklem who emigrated from Ørland, Norway to Eau Claire, Wisconsin in 1881. I have made contact with some of his decendants, among those one of his grandchildren. We are now trying to find the ancestors of Theodore's wife Gunda Halvorsen (1865-1948). I have found out that this Halvorsen family probably came to the USA in 1979, according to the US censuses of Eau Claire I have found so far. I have found that Gunda Halvorsen's parents probably were: Paul (Poul) Halvorsen born 1827 in Norway (census) Sophie (Sofie) Halvorsen (tomstone) I have found what I think is the family in the censuses in Norway both in 1865 and 1875. I still have to establish the link between the Norwegian Halvorsens and the Eau Claire Halvorsens. In this case information from Eau Claire censuses from 1880. 1885 (Wisconsin) and 1890 would help, as well as information about the family's voyage. In 1865 we find the following family in Borge: Poul Halvorsen, age: 38, born in Fredrikstad Sofie Kristiansdatter, age: 36, born in Borge Hans Poulsen, age: 5, born in Borge Oline Poulsdatter, age: 3, born i Borge Gunda Poulsdatter, age: 1, born in Borge In 1875 we find the same family in Orkdal: Poul Halvorsen, born 1827 in Fredrikstad Soffie Kristiansdatter, born 1829 in Borge Hans Paulsen, born 1860 in Borge Gunda Paulsdatter, born 1865 in Borge Hellena Paulsdatter, born 1867 in Borge Ole Kristian, born 1867 in Borge I can find them in the church records of Orkdal moving to the parish August 26th 1875, but I can't find church records of them moving from Orkdal to America in 1879, and I can't find them on any voyage. We know Gunda Halvorsen had a brother called Hans. I was in Eau Claire this summer together with my cousin, and I know Hans Halvorsen's wife was called Johanna. When I found them in the 1910 census of Eau Claire, Hans' father lived with Hans and Johanna, and his name was Paul Halvorsen (82). So, Gunda and Hans' father was called Paul, born around 1828. Since I also can find one son Ole Halvorsen (born 1874) living together with Paul Halvorsen in Eau Claire in the 1900 census, and also the fact that the tombstone of the Halvorsen family has inscriptions like "P. Halvorsen", "Sophie..." something and one "Hellene..." (probably the daughter born 1867) i feel I have come a long way establishing the fact that this is the family originating from Borge, Norway. I just wish that I could find the Halvorsens in Eau Claire earlier than 1900, since I know Theodore Wicklem and Gunda Halvorsen met and married in Eau Claire in 1881, and also I think finding them travelling across the Atlantic would help establishing/verifying the fact that we are talking about the right family.
