Ellie was a cocaine addict when she got pregnant with Peyton and decided to give her up; Peyton was adopted by Anna and Larry Sawyer. She agreed not to have any contact with her daughter, but she later decided she wanted to see her and finally managed to at the end of Season 2.
Ellie was a writer and pretended to be doing a magazine article on Peyton so they could meet up. When Peyton called the magazine they tell her there is no-one called Ellie Harp working there, and they know nothing about the article. Peyton began receiving emails from "WATCHMEWATCHU" and assumed they were from Ellie. Ellie showed up at Peyton's door and told her that she was her mother, and she didn't send any emails. At first, Peyton didn't believe her or trust her, especially after Lucas Scott caught her buying drugs. However, she was dealing with a recurrence of breast cancer, and the pills were actually for medical purposes. Peyton was about to change her mind after finding out about Ellie's condition but they fought again when Peyton found that she wrote an article about her. She told her to go away, and called her a liar. Haunted by dreams about her "Angel of Death" persona, Peyton found Ellie again and they bonded. They decided to make a CD to promote Haley's new song and raise funds to fight breast cancer. They finally managed to finish the CD but Ellie died the day the records were ready. Peyton spread her ashes on a place where Ellie had been to a music festival, the best thing she had remembered aside from her time with Peyton.
