Valeria was born someplace in either Great Britain or Ireland, and when she was eleven years old began attending Hogwarts School of Witchcraft and Wizardry, where she was sorted into Gryffindor House. She graduated at the end of her seventh year with good enough grades that she could return as a professor, and eventually rose to the position of Head of Gryffindor House. She died sometime prior to September 1991.
By 1991, several portraits of Valeria hung at the main halls of Hogwarts Castle, such as the Grand Staircase. In Gryffindor Tower, one of her Portraits guarded a secret passage to a disused bathroom. The password for said passage was "Pig Snout".
By the next school year, her place in the Gryffindor Tower had been taken by Oraclitus Spheer. Her portrait was moved to the Hogwarts Library Annexe, hiding a shortcut to a section containing the original hand-written manuscript of Hogwarts, A History, by Chroniculus Punnet. The password was "Bibliophile".
