Sarah Teatherton

Sarah Teatherton is the wife of Johnathan Teatherton, the mother of Alexandra O'Mackey, and the grandmother of Jules O'Mackey from The Sims 2: Seasons. Not much is known about her since she is only mentioned in the family tree of her descendants. Somehow or another, she was one of Morty Roth's major caretakers when he was growing up (as reflected in his memories).

Trivia
The reason it may appear that she raised Morty Roth is because his real mother has the same name as herself just slightly different spelling so it could be a simple creator mistake.
