St Margarets, London
St Margarets is an affluent suburb and neighbourhood in the London Borough of Richmond upon Thames, about 9 miles (14 km) west-southwest of central London. It is bounded by the Thames Tideway to the north-east, and the River Crane to the north-west and north where the land tapers between those rivers. Land and buildings closer to Richmond Bridge than the eponymous railway station are, traditionally distinctly, known as East Twickenham. Both places go by their post town and traditional parish, Twickenham quite often; in the 19th century the south of St Margarets was marked on maps as Twickenham
