Gjesling (or Gjæsling) is an old family from the area that is now VÃÂ¥gÃÂ¥ Municipality in Innlandet county, Norway.
In 1130 Ivar Gjesling was the earliest-known owner of the Sandbu farm, located just south of VÃÂ¥gÃÂ¥mo. He served as King Magnus IV's lendmann (governor) for the Oplands. Ivar Gjesling, allied himself with the Birchlegs (Birkebeinerne) â who chose Sverre as their King at the ÃÂreting in 1177. King Sverre granted him the valley of Heidal as a reward.
Sigrid Undset's fictional Lady Ragnfrid, wife of Lavrans, was created a Gjesling from Sandbu.
Gjesling descendants still own the farm Sandbu in the VÃÂ¥gÃÂ¥ region, Riddersandbu, which includes buildings built before 1600.
