“She would have also probably been amused that we have been to Downing Street and are now to meet a member of the Royal Family.”
Gillian and her niece Hannah started the charity four years ago, through which they collect donated handbags and fill them with toiletries for domestic abuse victims. To date, they have filled 15,600 bags for women in the UK and across the world.
Next year, she intends to apply for Love Grace to become an official charity.
The women said they would continue to raise awareness of violence against women so that other families do not experience what they did when Grace was murdered in Auckland in 2018.
O’Callaghan added: “We wanted to create a legacy in Grace’s memory and directly help women who have been affected by domestic abuse, to turn our negative into a positive.
“If we help just one woman, then we have achieved that.
“We have been overwhelmed by the support people have shown our ‘Love Grace Handbag Appeal’, from donating handbags and toiletries to running appeals in their own area.
The OBE comes days after Gillian Millane said in an interview that she was plunged into darkness after her daughter’s death and at one point contemplated killing herself.
“Grace had such a bright future and it was taken away from her and us,” she told the BBC.
“I will never see Grace in a wedding dress or see her grandchildren. This is a life sentence I’ve got. This is me until the day I die.”
But she said she eventually found the strength to keep going. “I will never get over it but I just know I’ve got to make the world a better place,” she said.
