As an appeal to send two boys to America to live with their aunt passes the £20,000 mark delighted organisers say they are certain of hitting their target.
Even if nothing else is donated to the crowdfunder website Jo's Last Wish staff at Edward Worlledge Primary School say there are enough events in the pipeline to ensure that the remaining £5000 is raised in time.
Jo Lynch died in July aged 29 thinking her two young sons Kallum Lynch, aged nine, and seven-year-old Jack Rayner would be cared for by her sister Sam Wells in Los Angeles.
But strict rules on immigration and trafficking mean the process was more complex and expensive than anyone had realised putting her wishes at risk.
Pledges to an online page this week topped £15,000 with cheques and cash bringing the total so far to over £20,000.
Linda Dickeson, who is co-ordinating the appeal at the school, said that even if nothing else was donated she was confident that enough had been done to raise the money.
A non-uniform day, cake sale, and raffle are being staged at the school next Friday with a family bingo event in the evening.
Then on April 22 a variety show will give a platform to local talent at Gorleston's Pavilion Theatre with all proceeds going to the fund.
Mrs Dickeson said all 73 staff at the school had been challenged to donate prizes for the various events and that dealing with the calls and inquiries had been 'just non-stop.'
Donations continued to come in from all over the UK as the boys's tragic story spread, she said, although much of the money had come from within Great Yarmouth which was heartening.
Meanwhile the boys are living with their grandfather Patrick Lynch in Shakespeare Road. The former caterer has endured the heartbreak of seeing his wife and two of his three daughters die from the same form of cancer. His own ill health means the boys' best hope of a future is with their only other surviving relative.
Kallum also battled the disease as a toddler and lives with the life-limiting consequences of treatment. He will soon need an operation on his back. Tests are on-going to see if Jack is also a carrier.
Mr Lynch said: 'I wish I could thank every individual person. The comments they have left have really bought a lump to my throat. We know the money is going to be there and that it will be spent on the adoption. I cannot believe this has all just happened in just a few weeks. People from all walks of life have donated.'
