Peder and Lukris Kirkebø, Bergen-Quebec, 1870

Peder (born 1828) and his wife Lukris (born 1838) Kirkebø from Ladvik parish, Sogn og Fjordane, Norway emigrated from Bergen, on the 22th of may 1870. They travelled with the boat Galathea to Quebec, Canada and had their son Christian (born 1868) with them. They may have settled in South Dakota, US, but I am not sure, any information will be very helpful.
