Just a quick reminder that tonight’s episode of “Who Do You Think You Are?” on BBC will be featuring JK Rowling and a look into her ancestry. The episode will air on BBC1 at 9pm BST.

Always intrigued by her late mother’s French ancestry, the Harry Potter author delves into her Gallic roots by visiting Edinburgh, London and Paris. Keen to find out why her great-grandfather, Louis Volant, was awarded one of France’s most prestigious medals for his actions during the First World War, the writer makes a surprising and shocking discovery. Even further back, she encounters an ancestor who triumphed against all the odds.
