Pop. of civil parish It lies in an open valley on the west (left) bank of the Ouzel, where the great north western road from London, the Roman Watling Street, crosses the stream, and is 1 m. E. of Bletchley junction. The church of St. Martin was built (1730) on the site of an older church at the instance of Browne Willis, an eminent antiquary (d. 1760), buried here; but the building has been greatly enlarged. A custom insti tuted by Willis on St. Martin's Day (Nov. I I), and still observed, includes a service in the church, the firing of some small cannon called the "Fenny Poppers," and other celebrations.
