Mrs Pettigrew (fl. 1981) was the mother of Peter Pettigrew. Following her son's alleged death at the hands of Sirius Black in 1981, she was given the Order of Merlin that was awarded to him posthumously. It is known that the biggest bit of Peter Pettigrew she received was his index finger. It is unknown whether she is still alive, or if she is aware of her son's duplicity.
