There were two farmsteads located at the main farm # 41 Skjeldal in Etne, Hordaland fylke as late as 1950 on the farm tax census taken then. Two also on the tax census of 1886. So if you would like to know which one of the two was your "home farm" perhaps a Bygdebok search would say which one Osmund came from. http://www.rootsweb.com/~wgnorway/lookups.html
The above weblink leads to a page that has lookups volunteers in the Hordaland section of the page which have the Etne farm and family histories in them. When you write to the Etne volunteers, ask for the Skjeldal farm if they can find your ancestor, and to tell you which one of the two farms it is. That will help.
