Farm Locations Hedmark

My Great Grandfather, Peer Vold (Peder Paulsen) was born 1817 on Vold Farm, Furnes, Hedmark, Norway. I have been able to confirm the farm was still in operation by his "cousins" around 1900. I would like to know where Vold farm is or was in Furnes. Was it acquired by another farm, become part of a town or city, or ??? Also Peder's father Pal Johannssen was born on Gresby farm, Hedmark. I presume this farm was in the vicinity of Vold farm. Does anyone have knowledge of or where I might find out what happened to this farm? Finally, my great-grandfather, Peer (Peder) operated an inn at Stavberg, Hedmark, for about 6 years. They had a daughter Caroline Gustava while living there. I presume this inn is in the vicinity of the current Hamar airport. ?? In all Peer and his wife Charlotte had 3 children, Pauline, Caroline, and Carl August. (My Grandfather Oscar August Vold [Levanger] was born out of wedlock, Peer being the father.) Ill heath plagued this extended family (many dying in their youth or early adulthood) and I don't know if Pauline and Caroline lived to adulthood. Carl is listed in the 1875 census, married and living in Oslo, but no further record of this family exist that I can find. Any information or additional resources would be helpful. thank you.
