Kit Harington was born on 26 December 1986 in Acton, London, to Deborah Jane (Catesby), a former playwright, and Sir David Harington, 15th Baronet, a businessman. His full name is Christopher Catesby Harington.His mother named him after Christopher Marlowe, whose first name was shortened to Kit, a name Harington prefers. Harington's uncle was Sir Nicholas John Harington, 14th Baronet and his patrilineal great-grandfather was Sir Richard Harington, 12th Baronet. The Haringtons are an ancient family that once spelled their name Haverington and derived the name from their estate, a lordship in Cumberland. The first person identified with their name was one Robert De Haverington, the son of Osulphus or Oswulf whose manor was Flemingby. Through his paternal grandmother, Lavender Cecilia Denny, Harington's eighth-great-grandfather was Charles II of England. Also, through his father, Harington descends from Scottish politician Henry Dundas, 1st Viscount Melville. He is related to people who were involved on opposite sides of the Gunpowder Plot. He claims a family connection with the leader of the plot Robert Catesby on his mother's side, while through his father's side, he was related to James I (grandfather of Charles II) the target of the assassination attempt, and Lord Harington who was in the Houses of Parliament that Catesby and his co-conspirators tried to blow up. Another relation John Harington (different branch of the family) observed at the age of 13 the displayed head of Catesby after his execution and later commented on it. Harington was a pupil at the Southfield Primary School from 1992 to 1998. When he was 11, his family moved to Worcestershire and he studied at the Chantry High School in Martley until 2003. He became interested in acting after watching a production of Waiting for Godot when he was 14 and he performed in several school productions.
