Mrs. Glegg is Mrs. Tulliver’s eldest sister and Tom and Maggie’s most hated aunt. She takes very seriously her rights and responsibilities as the oldest of the Dodson sisters, and tends to treat her family dictatorially, making loud judgments about Mrs. Tulliver’s housekeeping and criticizing everything about her niece and nephew’s behavior and physical appearance. Mrs. Glegg believes that the Dodson way of life is the highest standard to which others should aspire, and she frequently finds others wanting in that respect (particularly Mr. Tulliver, who she thinks is rude and hot-headed.) However, despite her irritable nature, she is the only Dodson family member who defends Maggie at the end of the novel, when Maggie has become an outcast as a result of her botched elopement with Stephen Guest. For Mrs. Glegg, family is the highest value, and she is fiercely loyal to her own kin.
