Farm name Knain

My great- great grandfather, Laurils Gulbrandsen, emigrated from Kristiania around 1868. The inscription on the trunk that he brought along from Norway says, "Laurils Gulbransen Knain til Wisconsin North Amerika". I was told by the curator at the Vesterheim that "Knain" is the name of the farm. I have not been able to find a farm by this name. Does anyone know of a farm by this name? Thank you,
