This time it’s Robert Catesby (1575-1605), one of the gunpowder plotters.
Apart from it not being my field, there are far better summaries of the Gunpowder Plot on the web than I could manage. Like this one, for instance.
Catesby died on 7 November, but no-one remember remembers that date!
Robert was a descendant of William ‘the Cat’ Catesby, who was executed after the battle of Bosworth.
