Kezia Horn, portrayed by well-known Mary Poppins actress Hermione Baddeley, appeared in a few episodes in seasons four and five of Little House on the Prairie. She first appears in Castoffs, then The Handyman and then a final appearance in The Lake Kezia Monster.
During her final appearance, Harriet Oleson tries to evict Kezia from her house, as she has fallen behind on taxes. Then Harriet, Willie and Nellie all move into Kezia’s house, with Kezia as a servant. At the end of the episode, a plan concocted by Laura, Albert and Andy about the Lake Kezia monster led to the Oleson’s fleeing in terror.
Kezia keeps her home, but she, unfortunately, is never heard from again, nor referenced in any later episodes. She is one of the many residents in Walnut Grover to make an appearance then is seemingly forgotten about, although her appearing in 3 episodes over more than one season is unusual for the show.
