Sir Henry Percy, also called Harry Hotspur (20 May 1364/1366 – 21 July 1403) was the eldest son of Henry Percy, 1st Earl of Northumberland, 4th Lord Percy of Alnwick. His mother was Margaret Neville, daughter of Ralph Neville, 2nd Baron Neville de Raby and Alice de Audley. His nickname, 'Hotspur', is suggestive of his impulsive nature. His date of death is known but not the exact year of his birth.
This is his statue situated in the Courtyard at Alnwick Castle (no, the Castle is not on fire, it's just my interpretation of him riding into battle!).
And for all you football fans, the Percy family owned large tracts of land in Tottenham with the local football club Tottenham Hotspur choosing the name Hotspur
