Alice Ghostley as Esmerelda

Esmerelda first appears in "Samantha's Yoo Hoo Maid" she is a witch who becomes the Stephen's housekeeper after Endora introduces her to her new maid suggesting she should have another witch as the housekeeper.  Esmerelda's powers as seen in her first episode appearance, appear to be fading as she often causes some trouble with her magic by mistake such as when she sneezes she usually conjures up something by accident, Esmerelda is seen in last few seasons taking care of Tabitha and Adam.  Esmerelda played by Alice Ghostley is considerbly the spiritual replacement for Aunt Clara because she was created after the death of protrayer Marion Lorne as the producers felt that the role of Clara could not be replicated by another actress.
