A heartbroken family say they have been visiting the wrong grave for more than 40 years.
Sylvia Ross, 67, buried her father John Thomas Thompson at Witton Park Cemetery in Bishop Auckland, County Durham, UK, back in 1979.
She says since then, she has regularly gone to see him and taken flowers to mark every birthday of the deceased, Father's Day, and Christmas day.
But she was given bad news that the burial site she has spent so much time at, was the coffin of a complete stranger, a man named Frederick Brown while her father was actually lying in an unmarked grave a matter of yards away.
Sylvia's daughter, Lynette, 42, said to Sun UK: 'She's heartbroken as she says her dad has laid there thinking not one of us cared about him, with no flowers and no visits, nothing.'
She added: 'We're disgusted, and my mam is heartbroken.
'I never met my grandad, but my mam has been visiting his grave for 43 years and is utterly devastated.'
The burial ground error only came to light when Brown's family contacted Durham County Council about putting a memorial up on their double plot.
The cemetery was run by Wear Valley District Council when John was buried but was handed over to Durham County Council in 2009 when it became a unitary authority.
Lynette explained: 'When my grandad died, mam called the council to ask them to put a marker where he had been buried so she knew which plot she was going to.
'They put it on the plot we've been visiting my whole life and have taken flowers to every birthday, Christmas, and Father's Day while he has actually laid there with nothing.
'It's just disgusting, how can they get something so simple so wrong.'
Graham Harrison, Durham County Council's bereavement services manager, said: 'We are sorry for the distress this error has caused the family.
'At the time, the cemetery would have been managed by Wear Valley District Council.
'Once we were made aware of the historic mistake, we carefully moved the items to the correct grave within the quickest possible time scale.
'Although the grave has now been corrected, this does not take away from the pain the family has experienced, and we would like to reiterate our sincerest apologies for any hurt that has been caused.'
