Charles had been greatly impressed by the determination of a poor young Welsh girl, named Mary Jones, who had walked 26 miles to purchase a Bible from him at Bala in 1800 and met with friends in London in 1803 to establish a society to make bibles ready available throughout the world.  Subsequently, the British and Foreign Bible Society was inaugurated the following year.

Charles later edited Welsh language versions of the First Testament and the Bible for the society.

On 7th March 1695, Sir John Trevor (from the Brynkinalt estate near Chirk in Denbighshire), Speaker of the House of Commons, was expelled for taking a bribe of 1000 guineas (£1.6 million in 2009).  He remained the only Speaker to be forced out of office until Michael Martin resigned in 2009.

Interestingly, Trevor was severely cross-eyed, which caused confusion as to which MP had "caught the Speaker's eye", and led to many speaking out of turn.
