Lancelot Blackburne, Archbishop of York (d. 1743)
Lancelot Blackburne (sometimes Blackburn, Blackborne or Blackbourn[e]; 10 December 1658 – 23 March 1743) was an English clergyman, who became Archbishop of York, and – in popular belief – a pirate.

He was described by Horace Walpole, in his Memories, as "…Blackbourn, the jolly old Archbishop of York, who had all the manners of a man of quality, though he had been a buccaneer, and was a clergyman; but he retained nothing of his first profession, except his seraglio."
