Ruth is Isabel’s 5 years old sister. She had a “simple mind” and suffered from epilepsy. She had been sold to Mr. and Mrs. Lockton with Isabel to be their slaves in New York. Mrs. Lockton had dressed up her like a doll, but soon she found Ruth had epilepsy and she thought there was evil in Ruth’s body. Finally, Mrs. Lockton told Isabel that she had sold her to West Indies, but in reality sent her away to their other estate in Charleston.
