Petunia Evans was the first born to her muggle parents in or prior to 1959. She had a younger sister, Lily, who was a muggle-born witch and only witch in her whole family. The family lived in Cokeworth, England.Petunia knew of her sisters powers and, when Lily received her Hogwarts invitation, wrote to Albus Dumbledore asking if she could also study there. Dumbledore kindly wrote back to her, explaining why she couldn't. Petunia felt left out and possibly jealous as her parents continuously praised Lily for her abilities. This lead Petunia to despise magic and the wizarding world. When she was around eleven, her sister became friends with a young wizard named Severus Snape. Because he was from a 'poorer' part of town Petunia looked down on him. Discovering he was a Wizard left her to dislike him even more, calling him and her sister freaks .At some point in the 1970s, Petunia left home to pursue a typing course in London. This led to her getting a clerical job, where she met Vernon Dursley, a junior executive whose complete ordinariness she found appealing. Vernon also took a fancy to Petunia and the two went on a number of dates. Vernon proposed to Petunia in late 1977 which she gladly accepted, but secretly worried what Vernon would think when he met Lily. She eventually told Vernon about Lily being a witch on a date, and while he was shocked, he assured her he would not hold it against her.The couple's first meeting with Lily and her boyfriend, James Potter, went poorly due to talk about magic, leading Petunia and Vernon storming out of the restaurant. Petunia and Vernon were married and settled at 4 Privet Drive in Little Whinging, Surrey by the end of 1977. Fearing that she would be overshadowed, Petunia refused to have Lily as a bridesmaid, which upset Lily. Petunia had little contact with her sister thereafter and she and Vernon chose not to attend James and Lily's wedding. Petunia and Vernon's only child, a son named Dudley, was born on 23 June, 1980. The couple took pride in being a normal family, unlike Lily's. The last piece of mail Lily sent her was an announcement of her son Harry's birth on 31 July, 1980, which she took one look at and promptly threw away.Everything changed on 1 November, 1981 when Petunia opened her door to find a baby on her doorstep. The child turned out to be her sister's son, Harry Potter. A letter had been left by Albus Dumbledore, explaining the circumstances of Harry's arrival, including the death of both her sister, Lily and her brother-in-law, James. As she was the only member of the family that had her sister's blood running through her, this ensured the protection of Harry and his family from Lord Voldemort and his Death Eaters. She reluctantly agreed to take her orphaned nephew into her home and family, taking the responsibility to not tell Harry or anyone else about the fact that Harry was a wizard. Petunia, however, did not treat Harry as a welcome addition to her family. A constant reminder of her sister and the world she herself had been excluded from, she treated Harry like a disease, even keeping him in the cupboard under the stairs as a bedroom for much of his childhood. She made a point of showering Dudley with gifts while completely ignoring Harry, although they were both around the same age. She forced him to do all of the chores around the house, while Dudley was free to do anything he pleased. Petunia also told Harry that his parents had died in a car crash and that the scar on his forehead came from that same accident. She did not let Harry ask any questions about his family.When Harry's Hogwarts letter arrived in 1991, she supported her husband's decision to keep the truth from Harry. They constantly tried to burn or rip up the letters, but they found that nothing was helping to stop the letters coming to Harry, so Petunia and the rest of the family moved to different places in an effort to outrun this wizarding post, until finally they were tracked down by Rubeus Hagrid. When Hagrid forced the issue of Harry's origin, Petunia lost control and let loose all of the resentment she'd held in about Lily's life. Over the next several years, Petunia still grudgingly permitted Harry to remain in her home over the summers, recharging the blood protections that kept him and her family safe from Voldemort throughout the rest of the year.In the summer of 1997, the blood protections were due to expire. Petunia, Dudley, and Vernon were placed under the protection of Dedalus Diggle and Hestia Jones, members of the Order of the Phoenix. Just before the group left Privet Drive, Petunia watched her son offer the first words of acceptance Harry had ever heard from a Dursley and she burst into tears on Dudley. Petunia walked towards the door to leave, looked back at Harry and opened her mouth to speak, but shortly after she pursed them back up and walked out. Petunia had wanted to wish Harry luck with his quest, but suppressed it and left Privet Drive with her family. They went into hiding from Death Eaters and Lord Voldemort.In later life, her only son Dudley married and had at least two children, making her a grandmother and mother-in-law to Dudley's wife. Harry has said to have been on Christmas card terms with Dudley and his family and went to visit them occasionally, which his children hated. Show less «
