Georgia's former headteacher Chay Davies, of Ercall Wood Technology College, is expected to read a tribute to Georgia during the funeral service.
Rev Mark Ireland, vicar of All Saints Church, said the large numbers of people paying the funeral will be comforting to Georgia's family:
"We are glad that young people of the town have turned to the church in this time of distress.
"We know it will be a great source of comfort for her family to see so many people coming together to celebrate Georgia's life."
