Political commentator Vincent Hanna played a character billed as "his own great-great-great grandfather" in the episode "Dish and Dishonesty" of "Blackadder the Third". Hanna was asked to take part because the scene was of a by-election in which Baldrick was a candidate and, in the style of modern television, Hanna gave a long-running "live" commentary of events at the count (and interviewed candidates and election agents) to a crowd through the town hall window.

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.
