One Quick Question- Rund Farm

Hey I have a quick question about farms in Norway- My ancestor Bjorn Trulsen Rund and his siblings came from Sigdal Parish, in Buskerud in 1879. I believe when I looked at the digitalarkivet that it said Rundskkoven - Is that the farm that they came from? Is that where my last name originated from? Is there more than one family that owned and worked on the same farm? What would they probably have farmed? It's kind of a little confusing...... Thanks Alot Megan
