Peter Grimm was a member of the Grimm Family who lived from 1840-1947. Like all members of the Grimm family, it can be assumed he was either a fairytale detective, or he was at least aware of the existence of Everafters. As he was born to a Grimm, Peter is a Grimm by blood. He was the husband to Alison Grimm I and had four children with her: Chloe Grimm, Edwin Grimm, Matilda Grimm and Basil Grimm. Peter is grandfather to Henry Grimm and Jacob Grimm, and great-grandfather to Sabrina and Daphne Grimm.
