In medieval times earldoms closely associated with counties, and the Earls of Winchester were sometimes referred to as Earls of Southampton (for Winchester is the county seat of Hampshire, which in those days was known as County Southampton or Southamptonshire).
The Isle of Wight, an island off the south coast of England, was part of the historic county of Hampshire (originally Southamptonshire), and was linked with it for parliamentary purposes until 1832, when it became a county constituency in its own right as it had also been during the Protectorate (1654–1659).
