Hi Rick!
I was able to find your Grandfather Jakob in the emigration database "Emigrants from Oslo 1867-1930". There it says your Grandfather had residence in Elverum, so it should be Heradsbygd near Elverum in Norway.
You can do the search online, at http://digitalarkivet.uib.no/cgi-win/WebMeta.exe (Source category=Emigrants, Sub-category=Registers)
