In Norway, families took the name of their farms as their surnames. Gudmundsrud (pictured at left) was the name of the farm that Nils Knudsen Gudmundsrud purchased in 1833 and sold to his son Nils in 1868.
Gjeldaker (or Gjeldokk) is the name of the farm that Nils K. Gudmundsrud bought in 1857 and sold to his son, Lars Gjeldaker, in 1869.
The farms were near Ål, Hallingdal, high in the mountains of central Norway.
