Mrs. Tranter is Ernestina’s aunt, with whom she stays in Lyme. She’s one of the most truly kind characters, and in her treatment of her servants, she acts as a counterexample to Mrs. Poulteney and Charles. She sees her servant Mary as a whole person who experiences pain and passion, and she does whatever she can to help Mary, Sam, and even Sarah. Ernestina often tries to rebel against her aunt, but Charles likes Mrs. Tranter.
