The 15-year-old from Royal Norwich won the English schools U16 championship and then followed up with victory in the flight two matchplay of the English girls championship.
Rebecca is the first Norfolk golfer ever to win a national schools title and she claimed it when she chipped in for an eagle and a one-stroke win over England girl international Heidi Baek (Felixstowe Ferry).
Rebeccas success at Tankersley Park, Sheffield, earns her a place in the team for the annual schools international against Wales on August 27.
This summer, she has also successfully defended her title as Norfolk girls champion and cut her handicap from eight to four within the space of two weeks.
