Eli Johannesdattter/Jespersen

Eli Jesperson was born in Norway on 3 Nov 1856. She immigrated to New Zealand and married Jons Svennson (John Swenson). They are my Great Grandmother and Great Grandfather. Eli was born on the farm Tormoen under Lundeby, Grue Parish, Solor. We are leaving New Zealand on the 18 July and will be in Norway from the 30 July to the 3 August. Staying at the Rainbow Terminus Hotel. I believe the area she came from is called Skarnes and is not far from Oslo. Any help with finding the farm Tormeon under Lunderby and Grue Parish by train would be appreciated.
