It’s an amazing statistic, but almost half the UK population is related to a British king or queen. Many families have whispered stories of such glittering connections passed down through generations, but the problem can be finding the proof.

So You Think You’re Royal? sets out to solve the mysteries and prove one way or the other whether ‘ordinary’ families can have very extraordinary royal roots. Every week a different family’s legend about their blood links to the monarchy is put to the test.

Historian Saul David takes each family on a very personal and often emotional journey of discovery. Delving into their social history he attempts to reveal the truth about a hidden royal association.

The genealogical research is carried out by Nick Barratt, who uncovers the records that can either prove the royal connection, or dash the family’s hopes. Giving the final seal of approval is Charles Mosley, Editor-in-Chief of Debrett’s, the recognised authority on the British aristocratic establishment.

Until you search you never know who lurks within your family tree - kings, queens, dukes and princes perhaps, or just generation after generation of peasants and paupers! So You Think You’re Royal? uncovers the truth, once and for all.

In the first episode housewife Geraldine Cummings has always been told by her father (an Irish bricklayer) that they were related to Grace Kelly - the Hollywood icon turned real-life princess. With the help of Nick Barratt, Geraldine and her family go on a journey that will take them as far as Monaco in order to prove their story.
