Mrs Warfield Simpson

It seems that B. B. Warfield had a pretty extraordinary family. According to Thomas G. Reid, Jr.:

His mother was Mary Cabell Breckinridge, a descendent of John B. Breckinridge (1760-1806), a United States Senator and Attorney General under President Thomas Jefferson. Her father was the prominent Presbyterian preacher Robert Jefferson Breckinridge (1800-1871), and her brother, John Cabell Breckinridge (1821-1875), was Secretary of War in the Confederate Government.

Benjamin’s father, William Warfield, came from English Puritan stock, his forebears having fled to North America to avoid persecution. The Warfield family, in the person of Bessie Wallis Warfield Simpson (1896-1986), would later plunge the British royal family into its greatest twentieth-century crisis.
