New light was shed on victims of the 1953 floods hours after a new heritage centre opened in the town where they were swept away by the sea.
Russell Martin, his wife Dorothy and their young boys Russell Jnr and John all perished when the sea smashed into their chalet on South Beach Road in Hunstanton.
Until today, they were believed to have all been Americans, as Mr Martin served in the US military at RAF Sculthorpe.
But when his neice Joanne Ellis travelled from Lancashire to Norfolk to pay her respects and see if she could find out more about her relatives, she found the town's newly-opened heritage centre, where she spoke to local historian John Maiden.
Miss Ellis, 50, said her aunt Dorothy came from Lancashire and her cousins - aged just 22 and 11 months when they died - were born in England.
"She was only 22 when she died," she said. "They thought she was American, but she was born here. Her mum and dad didn't talk about it, they were devastated." Mr Maiden, chair of Hunstanton Civic Society, said: "It's blown me away to see Joanne and get her first-hand knowledge.
"We have a lot of information we share with other people, people come in and share their information with us and fill in the gaps."
Miss Ellis was one of more than 100 visitors to the new heritage centre, on Northgate, which opened this afternoon.
Volunteers have spent four months converting the former Natwest Bank they were given by an anonymous benefactor after they had to leave their previous home on The Green.
Its displays chart the town's history from prehistoric times to today, with displays featuring the coming and going of the railway, he town's pier and built heritage, along with the floods which claimed 31 lives in the town. The bank's former vault has been converted into a cinema.
Tony Armstrong, one of the volunteers who converted the building, said it had been hard work.
"We're all OAPs, we're all retired, so we didn't work 10-hour days," he said.
The centre is open on Saturday, Sunday Wednesday afternoons (1 - 5pm). Admission is free.
