Anne de Bourgh's vigilant companion, whose quiet attention makes the heiress's frailty the governing fact of every Rosings room.
Mrs. Jenkinson is the resident companion who attends Anne de Bourgh at Rosings Park. At the first dinner she is occupied with watching how little Anne eats, urging different dishes, adjusting a screen before her eyes, and worrying that she is indisposed. During cards she continues to monitor whether Anne is too warm, too cold, or has too much or too little light.
She speaks little beyond this care, and her own appearance is called unremarkable. Her role nevertheless makes visible the careful, enclosing management of Anne's sickly life under Lady Catherine's roof.
Nothing remarkable is said of her appearance. She is an English female companion whose age, face, hair, complexion, build, and dress are not described.
She is Anne de Bourgh's practical guardian of comfort within the highly managed household at Rosings.
