Tong Castle was a very large mostly Gothic country house in Shropshire whose site is between Wolverhampton and Telford, set within a park landscaped by Capability Brown, on the site of a medieval castle of the same name.

Colonel William Careless was a Royalist officer of the English Civil War. It has been estimated in various written sources that he was born c. 1620, however, it is more likely that he was born c. 1610. He was the second son of John Careless of Broom Hall, Brewood, Staffordshire, and his wife Ellen Fluit. He is chiefly remembered as the companion of King Charles II when the fugitive monarch hid in the Royal Oak following his defeat at the Battle of Worcester. His surname was changed to Carlos, the Spanish for Charles, by order of Charles II. He died in 1689.
