Anna is the head housemaid at Downton, primarily responsible for tending to the three sisters Mary, Edith and Sybil. A sweet and caring person, she doesn't hesitate when it comes time to help Lady Mary out of a particularly huge jam -- never mind the potential consequences. Anna is a welcome and reliable ear for Lady Mary, in particular, although there is never any question about the hierarchy in their relationship.Anna comes from a background of tenant farming and service. She feels she may have missed her chance at marriage. She is clever and resourceful, a thoroughly sympathetic character, which is generally appreciated (if not always) by Mary and Edith. She also is among the first of Downton's household staff to foster a connection with Mr. Bates.
