Jonathan Randall, commonly known as “Black Jack”, was a minor knight in England during the time of the Jacobite Rising of 1745. He played a part in quashing the rebellion, and was heavily financially supported by the Duke of Sandringham. In 1746 Randall married Mary Hawkins, who bore him a son, Denys. Frank Randall, a historian and husband to Claire Beauchamp Randall in the 20th century, traces his family history back to Jack Randall.
Didn’t Black Jack Randall bugger the hero, James Fraser in Outlander?
