What do you mean by "doesn't exist"? It's not unheard of that farms, crofts etc in Sweden have biblically inspired names, see Dalkvist's comment on https://www.openstreetmap.org/changeset/49063557 for more. Judging from aerial photos, it's possible that the building has been demolished, but there's still a clearing in the forest that could be referred to by name.
