Mrs. Dursley was the wife of Dudley Dursley; the couple had at least two children. When her husband's cousin Harry Potter visited them with his family, their children would play while Dudley and Harry sat together quietly.
She is related to the Dursley family, and the Evans family who are the maternal family of her mother-in-law Petunia. She is related to the Potter family due to her marriage to Dudley Dursley, whose cousin is Harry Potter, and is related to her own maternal and paternal family.
It is unknown as to whether she knows the truth about Harry and his family being wizards or not.
