Analysis of information sources in references of the Wikipedia article "Ignatius Sancho" in English language version.
Until now, the first black voter in Britain was thought to be the composer Charles Ignatius Sancho, the British abolitionist who, as the owner of property in Mayfair, voted in the 1774 Westminster election. But a chance discovery at the British Library by Dr Gillian Williamson, a historian researching lodgers in Georgian London, reveals a black man voted in an election 25 years earlier. The revelation that John London, landlord of a pub in the capital, cast a vote in 1749, sheds new light on an era when the black population of London is believed to have been 10,000 strong, and the democratic process was limited but lively.
