William Catesby

He served as Chancellor of the Exchequer, and as Speaker of the English House of Commons during the Parliament of 1484, in which he sat as knight of the shire for Northamptonshire.

[3] In July 1484, William Collingbourne, a Tudor agent, tacked up a lampooning poem to St. Paul's Cathedral, which mentions Catesby among the three aides to King Richard, whose emblem was a white boar: The Catte, the Ratte and Lovell our dogge rulyth all Englande under a hogge.

)[4][5] The poem was interpolated into Laurence Olivier's film Richard III, a screen adaptation of William Shakespeare's play.

William Catesby was one of the two councillors (the other being Richard Ratcliffe) who are reputed to have told the king that marrying Elizabeth of York would cause rebellions in the north.

Catesby was succeeded by his eldest son, George, to whom the family seat of Ashby St Legers was later restored.
