Who is Susanna Endicott from I, Tituba, Black Witch of Salem and what is their importance?

Susanna Endicott is the elderly white woman for whom John Indian works as a slave in everything but official name. He believes that she sees him as much as a companion as a servant, but her treatment of Tituba and eventual treatment of John clearly suggests otherwise. Susanna is rigid, judgmental, and vindictive, characteristics that trigger Tituba's first efforts at using her "powers" for revenge". She (Susanna) can be seen as the first of several portrayals of white Christian narrowness and authority throughout the narrative.
