In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Milton like this:
MILTON, a hamlet in Prittlewell parish, Essex; close to Southend. Real property, £7,650; of which £570 are in fisheries. It was anciently a separate parish; but ceased to be so in consequence of part of it being swallowed up by the sea. Its church continued to be visible at low-water mark in the last century.
