A cheque for £13,000 has been handed over to Hammersmith hospital in West London.
The money is the proceeds from the Rosie Williams Golf Day, which took place Northwood golf club in Middlesex in October.
Mayo born Rosie Williams lost her battle with ovarian cancer in 2008.
Her good friend and golfing partner Bridie Fitzpatrick, also from Mayo, decided to get together with Rosie's family and their golfing friends to organise a golf day in her memory.
The day has become an annual event taking place on the first Thursday of October, close to Rosie's birthday and anniversary, and money raised goes to support research into Ovarian Cancer at Hammersmith hospital.
