Declan said the family was planning to create a video montage of Millane and asked those who had photos of her to contribute.
"Please feel free to send us any photos, videos, or a memory that we could share with everyone and cherish forever," he said.

Police declined to comment as to whether any representatives would be attending funeral.
Millane's father David and her uncle travelled to New Zealand to help find her. Her body was discovered a week after she went missing.
Shortly after arresting the 26-year-old, police also made an appeal for the sighting of a 2016 red Toyota Corolla hatchback.
The car was rented and returned to a central Auckland rental car company after her death.
Police said the vehicle was located in Taupō but not driven there by her alleged killer.
"After the disappearance of Grace on 1st December 2018 our whole world turned upside down ... we would like to thank the people of New Zealand for their outpouring of love, numerous messages, tributes and compassion.
"Grace was not born here and only managed to stay a few weeks, but you have taken her to your hearts and in some small way she will forever be a Kiwi."
