Grace Antonia Helen Hutchinson was born in October 2005, two months early, to Tony Hutchinson (Nick Pickard) and Mandy Richardson (Sarah Jayne Dunn). Grace was originally going to be called Antonia but Mandy was not keen. Antonia was then made her middle name. Mandy suffered postnatal depression for a while. But after she spent a while in intensive care, Mandy made friends with a woman who had a premature baby called Daisy. Daisy died and Mandy grew to love Grace in fear of losing her. Grace was christened, where Becca Dean (Ali Bastian) became her godmother, while Max Cunningham (Matt Littler), OB (Darren Jeffries) and Dom Reilly (John Pickard) became godfathers. On 12 May 2006, aged six months old, Grace was found dead from suspected SIDS, on a night Hannah Ashworth (Emma Rigby) and Nancy Hayton (Jessica Fox) were babysitting, which left the girls traumatised, after thinking it was their fault. Soon after Grace's death, Mandy left Hollyoaks in the hope of moving on and subsequently left a heartbroken Tony behind, after he had told her that it was all her fault that their daughter died that night.
Following her death, Grace has been mentioned several times. Tony and Jacqui McQueen (Claire Cooper) miscarried a baby in 2007, thus reminding Tony of Grace. In 2013 whilst speaking to Sinead O'Connor (Stephanie Davies) he tells her about Grace and that not a day goes by that he doesn't think about her. Mandy met another man and gave birth to a girl named Ella. Grace appears as a vision of Tony's in Hollyoaks Later in 2013, along with fellow deceased character Kurt Benson (Jeremy Edwards)
Tony had affair with Sinead on her death anniversary, and she is mentioned in 2015 as well after the baby swap involving Tony's and Diane O'Connor (Alex Fletcher) baby Dee-Dee and Tegan Lomax (Jessica Ellis) daughter Rose came to light. Tony mentioned that losing Dee-Dee would be like losing Grace all over again.
