Nellie took after her doting mother Harriet (Katherine MacGregor), while father Nels (Richard Bull) tended to be stern with his two children and had little tolerance for Nellie's often cruel antics. Nels and Harriet frequently conflicted on the rearing of both Nellie and Willie; Harriet's assertiveness frequently won out, although Nellie was not always allowed to get away with her behavior.
