After the failed Monmouth rebellion in 1685 My great-great-great-great-great-great-great-great-grandfather did indeed preside over the Bloody Assizies in the old Manor House at Chard, in Somerset. His name was Judge JEFFERIES, which would fit in well with your clue.
Judge Jefferies was also known as the hanging judge, feared the breadth of England. There is an old saying: 'From Hell, Hull and Halifax may the Good Lord protect us' which refers to his 'patch' between Hull and Halifax. He once hanged more people in one day than any other judge had hanged in their entire career! If, like me, you ever wondered why, it's because he was trying to curry favour with the King.
