Tessie was a great-aunt of the Weasley children. It is unknown if she was a Weasley, or if she was related through another family, such as the Prewetts. In December of 1994, Ron Weasley commented that his dress robes for the Yule Ball made him look and smell like her. She may have owned Shell Cottage before Bill Weasley and Fleur Delacour.
