The whole area was once simply known as Stepney Marsh; the name Isle of Dogges first occurs in the Thamesis Descriptio of 1588, applied to a small island in the south-western part of the peninsula. The name is next applied to the Isle of Dogs Fam (originally known as Pomfret Manor) shown on a map of 1683. At the same time, the area was variously known as Isle of Dogs or the Blackwell levels. By 1855, it was incorporated within the parish of Poplar under the aegis of the Poplar Board of Works. This was incorporated into the Metropolitan Borough of Poplar on its formation in 1900 (thank you Wikipedia!)
