Kirsty, 11, seeks more Kirstys to help raise money for brain tumour research

Kent schoolgirl tracks down 10,000 namesakes as part of campaign – but non-Kirstys are welcome to donate too

Calling all Kirstys! A schoolgirl from Tunbridge Wells in Kent is seeking people who share her name to help raise money for research into paediatric brain tumours like the one for which she is being treated.

Kirsty Waugh, who turns 12 on Monday, has already persuaded more than 10,000 Kirstys, Kirsties, Kersties and assorted other variants to plot their locations on a map that shows Kirstys can be found everywhere from Colombia to Malaysia, and even at the Rothera research station in Antarctica.
