Idris Oakby was born in 1872 to parents of unknown blood status, in an unknown country, therefore, nothing is known of her upbringing or education. In her adult life, she set up a charitable organisation called Society for the Support of Squibs which supported Squibs and helped them live in the Wizarding world. She may have been frowned upon by other wizards and witches for her charitable work, considering how poorly Squibs are generally viewed in the magical world. However, it also possible she was commended by witches and wizards for her raising of awareness of the second-class status of Squibs and efforts to aid their difficult lives. This was reinforced by her posthumous award of "Witch of the Month".
