Schoolgirls as young as eight and parents who had come to pick up their children were also among those killed in Monday’s suicide bomb attack at Manchester Arena
The youngest person known to have died is eight-year-old Saffie Roussos, who was at the concert with her mother. Another young victim is thought to be schoolgirl Megan Hurley.
Here is what we know so far about the victims and the missing:
Georgina, from Chorley, was in her second year of studying health and social care at Runshaw College in Leyland, Lancashire, and had previously been a pupil at Bishop Rawstorne Church of England Academy.
The college, which confirmed her death, spoke of its “enormous sadness”, saying: “Our deepest sympathies, thoughts and prayers go out to all of Georgina’s family, friends, and all of those affected by this loss.”
The youngest known victim of the atrocity, eight-year-old Saffie had been at the concert with her mother, Lisa Roussos, and sister, Ashlee Bromwich, who is in her 20s, from Leyland, Lancashire.
They are both now in separate hospitals being treated for injuries, friends said.
Chris Upton, headteacher of Tarleton Community Primary School in Lancashire, said: “Saffie was simply a beautiful little girl in every aspect of the word. She was loved by everyone and her warmth and kindness will be remembered fondly.
Mr Atkinson, 26, from Bury, was named by friends on Facebook as a victim.
A fund for his family set up by friends has raised around £5,000
Hayley Turk, who organised the fund through website GoFundMe, wrote: “John was one in a million and loved by so many. A true gentleman.”
The 29-year-old PR manager, who had appeared on TV shows Come Dine With Me and Tattoo Fixers, was killed days before leaving for a two-month trip to the US.
Mr Hett’s brother, Dan Hett, confirmed his death on Twitter, saying: “They found my brother last night. We are heartbroken.”
Russell Hayward, believed to be Mr Hett’s partner, paid tribute to him, saying: “We got the news last night that our wonderful iconic and beautiful Martyn didn’t survive. He left this world exactly how he lived, centre of attention.
“I’m in a really bad way so please forgive if I don’t reply. Thankfully I have this wonderful family and amazing friends to keep each other strong. I love you Martyn. I always will.”
Olivia, from Bury, Greater Manchester, was among the first of the terrorist’s victims to be named.
The 15-year-old went to Tottington High School and had been to the concert with her friend, Adam, who has received treatment in hospital.
Olivia’s family had spent Tuesday frantically searching for her, but in the early hours of Wednesday Charlotte Campbell revealed her daughter had died in the blast.
Alongside a photo of Olivia she wrote on Facebook: “RIP my darling precious gorgeous girl Olivia Campbell taken far far too soon go sing with the angels and keep smiling mummy loves you so much.”
Kelly Brewster, from Sheffield, South Yorkshire, was reported by friends and family to be among those killed in the attack.
Her partner, Ian Winslow, later wrote on Facebook: “Not sure how this works but it isn’t good news. Kelly Brewster wasn’t one of the unidentified hospital patients. She has sadly passed away in the terror attack yesterday.
“Kelly really was the happiest she has ever been and we had so many things planned together. My daughter Phoebe will be absolutely devastated like we all are.”
Schoolgirl Megan Hurley is also understood to be among the dead.
The youngster was a former pupil of Halewood Church of England Primary School in Liverpool.
The Liverpool Echo reported that the chair of governors from the school attended a memorial service to the bombing victims at St Nicholas’ Church in Halewood on Tuesday, where he said Megan’s brother was also “seriously injured”.
