Jehanshaven

Is there or was there such a farm? In my family notes I have: The farm lies up in "LIOM" (the lee of the mountain) in Plassen Circuit, about 5 kilometers from Alvdal railroad station. The name of the farm is "LIEN" but is known colloquially as Jehanshaven. On the other hand it is listed in the registry (or register) as "PEDER'S PLAUSSEN". Both Peder's Plassen and Jehanshaven are named after the first settlers. The name Johan was pronounced Jehan in olden days. Jehanshaven was built shortly after the Louise smelter was constructed (1748) by one Peder, who worked at the smelter (copper). But the history of the farm is not known before 1793. In this year Johan Anderson became the owner. He was born in Grimsbo (Hennigarn) and was married to Giskin. Johan would be my great great great grandfather. If you have any information on the farm, I would appreciate hearing from you. Judie
