Godric of Finchale (or St Goderic) (c. 1065 – 21 May 1170) was an English hermit, merchant and popular medieval saint, although he was never formally canonised. He was born in Walpole in Norfolk and died in Finchale in County Durham.
In the Harry Potter books by JK Rowling, Godric Gryffindor is one of the four founders of Hogwarts. Gryffindor house students are usually distinguished by their courage and bravery. This is the house that the majority of 'good' characters in the books belong to (eg Harry, Hermione, the Weasley family, Neville etc).
Also in the Harry Potter books, there is a village called Godric's Hollow, where Harry's parents, Lily and James, lived. Harry is expected to return there in the last book.
