A heartbroken father and husband said his life had been "destroyed" after his wife and daughter were killed when a car headed the wrong way up the A1 and smashed into their vehicle.
Ian Richardson, 37, and his three-month-old baby Ava survived the horrific collision which happened at about 9.30pm on Sunday near Gosforth, Newcastle.
He chose to donate the organs of his beloved six-year-old daughter Mya, and he paid tribute to her and his wife Joanne, 40, calling them his "two wonderful girls".
Mya, with blonde curly hair, had just been chief bridesmaid at her uncle Simon's wedding in Dundee and Mr Richardson was driving the family home to Billingham, Teesside, when the devastating crash happened.
Mrs Richardson died at the scene and Mya, who suffered head injuries, died the next day in hospital.
Her husband, who works in marketing, said: "My life has been destroyed and my girls have been taken from me before their time.
"The only light I have now is my baby Ava. She gives me the focus to carry on and begin again."
Mr Richardson released a photograph of the four of them taken that weekend at his brother's wedding.
He also issued a picture of him, his wife and Mya at their own wedding in 2008, eight years to the day after they met.
Mr Richardson, still recovering in hospital with Ava, said: "Mya was a great kid, so full of life and spirit."
