Holly Wells and Jessica Chapman, both aged 10, were murdered by Huntley
She was brought up by another man – her mother’s husband Martin Bryan – and said she was relieved her mum “stepped out of his shadow”.
Describing the moment she released her link to the double child murderer, Grimsby native Ms Bryan said: "When I got to the name Ian Huntley it meant absolutely nothing to me, nothing at all. I entered his name into Google and started scrolling through pictures of him.
“There were headlines calling him a 'cold-hearted child killer', that sort of thing. Then one picture jumped out at me.
“Although the faces were pixelated I knew instantly one was my mum. And the little girl standing beside her was me at about ten.”
Huntley is serving life in prison for the murders
The traumatised youngster ran home from school and was then told she was Huntley’s daughter.
She said the revelation felt “like being thumped in the chest”.
Former school caretaker Huntley – who murdered 10-year-old girls Holly Wells and Jessica Chapman in 2002 – is currently serving a life sentence at HMP Frankland in County Durham.
Huntley was caretaker at Soham Village College
And his sickening crimes have had a lasting effect on his daughter, who said her infamous parentage had seen her spurned by past boyfriends.
She told the Mail on Sunday: "One boyfriend, once he found out, told me he didn't want to be with me because I might turn out like my father.
“Another told me he no longer wanted to see me in case my father was ever released, as he feared he would come and kill me.”
The trainee paramedic – who says she has no desire to ever speak to Huntley – added: ”When I go into a new relationship I wait until I see if it is going somewhere and if I feel comfortable in the boy's company.
“Then I say, 'There is something you might want to know about me'. It's never easy but I know I have to do it.
