Marjorie Dursley

Marjorie "Marge" Eileen[1] Dursley was Vernon Dursley's elder sister[1], sister-in-law to Petunia Dursley, and the aunt of Dudley Dursley. She had a career in breeding bulldogs. Ripper, a particularly ferocious bulldog, was her favourite.

Marge was a spoiled, unpleasant and arrogant woman, whose wealth appeared to be great, as she gave her nephew Dudley expensive gifts. In 1993, she visited her brother Vernon for a week. She enraged Harry Potter when she spoke ill of his parents. This caused Harry's magical abilities to unintentionally erupt, which resulted in her body inflating. Her memory of this incident was later purged by the Ministry of Magic.
