Three different Norwegian family lines connect to the Obernolte Family. These are the families of Thea Matilda Onstad, Rudolph Furgeson and Mabel Olson.
Thea Matilda Onstad's family came from the area around Øystre Slidre.
Ole Furgeson was born in Wisconsin the year his parents, Kittel Folgvartsen and Margith Pedersdatter arrived in the US from Norway with his older brother Peder. The family name evolved from Falgaasan in the 1860 census to Furgeson in the 1870 census.
The Furgeson's (Folgvartsen's) came from the Deelkaas (Deilskås Su-Tveitan) farm near Heddal (now Notodden) in the county of Telemark. Many of the baptisms, marriages and funerals linked below took place at the famous Heddal Stave Church which was built in the 13th century.
Helene Grasdalen's father's family came from Tinn in the county of Telemark. The Grasdalen Farm is located on Tinnsjoen (Lake Tinnsjø) which was the location of the sinking by the Norwegian Resistance of a railroad ferry carrying Heavy Water for the German nuclear weapons project during WWII. (The Norwegian Industrial Workers Museum exhibits information on this.)
Helene Grasdalen's mother, Ragnild Moen Gislesdatter, came from from Sigdal in the county of Buskerud.

Historically, Norwegian children were referred to as the son or daughter of their father. Women retained this even after marriage. Thus, Marie the daughter of Hans Pedersen would be know as Marie Hansdatter. Her brother, Ole, would be Ole Hansen. Occasionally the name of the farm on which they were residing would be added to the name to clarify which family was being referred to. By the 1880's or later, there was a change to dropping the 'datter' usage for girls and women thus referring to all children as 'sen'. The siblings Marie and Ole would then be Marie Hansen and Ole Hansen.
