HARRY Potter stars Emma Watson and Rupert Grint could be kissing cousins.
The pair share a steamy snog in the next film.
But ancestry experts have found they could be relatives from the village of Kilworth, Leics.
Family history researcher Nick Barratt traced the family trees of Emma, 20, and Rupert, 22, and found that more than 200 years ago their families had links to the village and could even be related.
Nick, of ancestry magazine Your Family History, said: “It is very rare to take two people who have no other connection and find they have a link to a small village like this.”
He described the coincidence as “amazing.”
Rupert’s paternal line stretches back to 1792 when distant relation William Berridge was born in North Kilworth.
Nick uncovered a branch of Emma’s family were the Bonsors of South Kilworth, who established a brick-making business in the early 19th century.
Rachel Root, 70, a local historian, said: “The Bonsors were a big family round here, as were the Berridges.”
Rupert, who plays Ron Weasley, hooks up with Emma’s character Hermione Granger in Harry Potter And The Deathly Hallows, out next year.
