Elizabeth Cooper won £5,400 in the Kent, Surrey & Sussex Air Ambulance's lottery, just nine years after her father George scooped the jackpot.
She even collected his winning cheque for him back in 2006.
Although her father died six years ago, the 63-year-old, from Dover, continued to play the lottery with his favourite digits. George had selected the numbers using loved ones' birthdays.
Elizabeth told the Dover Express: "It's amazing because when you contribute to these things you never expect to win anything.
"You always expect it to be someone else. They say lightning never strikes twice but anything can happen."
Her local paper reported she plans to use her winnings to take her mum on a luxury cruise.
And kind-hearted Elizabeth is also donating a portion of her prize money to the Ted Girdler Memorial Scholarship – a scheme set up in memory of the pilot killed in 2000 at the Eastbourne air show.
