Edmund Blackadder who shot Harold II at The Battle of Hastings. Blackadder is a genuine surname, its usage in the UK currently documented back to the 15th century, which may explain the choice of the name, with the first series being set in this time period. The name is thought to be mostly Scottish in origin, which is not contradicted in the series, as the first Blackadder begins as the Duke of Edinburgh. In the third series it is revealed that a branch of the Blackadder family is a significant clan in Scotland, although they have become known by the name MacAdder.
Blackadder the past to do a fifth series, set in the 1960s (centred on a rock band called the "Black Adder Five", with Baldrick – a.k.a. 'Bald Rick' – as the drummer). In the documentary "Blackadder Rides Again", Robinson stated that the series would present Blackadder as the bastard son of Queen Elizabeth II and running a Beatles-like rock band. Rowan Atkinson, Tony Robinson, Hugh Laurie, Stephen Fry, Tim McInnerny and Miranda Richardson would have reprised their roles, and reportedly, Brian Blessed, Elspet Gray and Robert East would have returned from the first series to play Blackadder's biological family.
