Edward Stanley was born in 1775. He was the rector of Alderley who was visiting Mr. Buxton in Mount Street in Manchester on 16th August, 1819. Therefore Rev. Stanley was in the same house as William Hulton, William Hay and the other magistrates. As Stanley was not a supporter of parliamentary reform, but at the same time not involved in the suppression of the demonstration, he was seen as an independent witness. Rev. Stanley observed the Peterloo Massacre from the room immediately above the one in which the magistrates were assembled overlooking St. Peter's Field.
