The name in Rygh «Norske Gaardnavne» was derived from Vidarstadir, where the man's name Vidar creates the stem.
The farm was the largest in Mo with a tax on 6 tn ½ quarter tnK [6 1/8 tnK]. Moland vicarage owned the little half quarter tonne (barrel) while the rest was allodial property.
Tjøstov, or Kiøstolff as he was entered on the tax lists, used the farm in 1593. He was alone at Vistad, but taxed only for a half farm. There may have been more users who were not on the tax lists.
