George FitzRoy, Earl of Euston (1715–1747) was an English aristocrat and politician who sat in the House of Commons from 1737 to 1747.

[1] In the biography written in the History of the Parliament, Lady Boyle was described as "a girl of the softest temper, vast beauty, birth, and fortune."

After she died on 2 May 1742, her mother said that Dorothy was relieved of the "extremest misery", that Lady Boyle's husband exacted on her as what is described as "utmost brutality".

The tenant stated that he had already paid the full rent owed, but would be willing to pay extra if that was what was needed, to which George responded by threatening to have the man's family removed from his residence.

In autumn 1744, FitzRoy eloped to Italy with a Miss Nevill, a celebrated beauty with a fortune to her name, and promised her marriage, which never materialised.
