Polly is Mr. Branghton’s youngest daughter, Tom and Miss Branghton’s sister, and Evelina’s cousin. Polly is a silly, uneducated girl who flirts openly with her lover, Mr. Brown, even though this was considered very improper behavior for women at the time. Polly is portrayed as more good-natured than Miss Branghton (who is moody and jealous of Evelina), but she’s also ignorant and careless about her reputation. At one point, she and Miss Branghton walk off by themselves in a public garden at night and are accosted by several young men—behavior that others view as extremely scandalous.
