Clarice Blackburn as Mrs. Johnson
Sarah Johnson was Bill Malloy's housekeeper until his death in 1967 (46, 53). She began working at Collinwood as the housekeeper originally as a spy, but eventually began to love the Collins family.
After Mr. Malloy's death, she originally believed that Roger Collins was responsible for his death (67, 69).
Family
Mrs. Johnson had a married daughter who lived in Boston (48, 72) as well as a sister she rarely visited (493). Her son, Harry came to visit her at Collinwood (471) and was offered a place to stay. She was very suspicious of him and often warned him to behave or he would have to leave. She accuses him of stealing food (542) which he was taking to Adam who was being hidden in the West Wing under orders from Carolyn Stoddard.
The Dream Curse
Julia Hoffman passed the Dream Curse on to Mrs. Johnson (490), who refused to go to sleep while caring for David Collins because he had lost his voice due to a curse by Cassandra Collins, aka Angelique (492). This greatly frustrated Angelique's plans and she had to figure out another way to "silence" David (493). Once David's voice was restored she successfully resisted passing the curse on to him quite a while, even planning a trip to Boston to see her sister (493), until she finally had met him outside the Old House (497), having been sent there by Cassandra.
1995
When Barnabas and Julia traveled to 1995, Mrs. Johnson was one of the few people they recognized who was left near Collinwood. Mrs. Johnson was very frightened by them because they had not aged, unlike she and Carolyn (1061). While Barnabas and Julia were trying to find out what happened to Collinwood while they were gone, Mrs. Johnson died at the foot of David Collins' grave (1064). Presumably when the destruction of Collinwood was prevented by the trip to 1840 it also prevented her death.
Life
Mrs. Johnson made her own mayonnaise (72), but in general her "boiled dinner" was the subject of much ridicule behind her back.
