Farms around Rørøs

My current research up my family line has taken me to the Rørøs area in the 1700's and in particular Bakken and Kuraasen farms. Is anyone aware of an on-line resource for the farms in the Rørøs area? I found the Wiki-Strinda to be very useful for the Strinda area farms (Tesli, Jacobsli) and hoping to find something anything for Rørøs. So far I haven't had much luck in my google searches. Or perhaps there is a book I can order? I have a wonderful book on the farms in the Ringebu Area that was given to me on a visit there. Thanks, Michael
