I can't help you with the actual guiding, but i can give you the coordinates: *58° 9'20.49"N, 13° 1'44.17"E*
Type that into Google earths Fly to feature without the *s and you will end up at the right place.
This is an unknown area for me but perhaps there are some local history/genealogy society that can offer some real help. :)
And I thinks that Törestorp/Thorestorp is a small village not a farm.
Below is a map from 1809. A plugin is required though.
