Rebecca (born 24th May 1897) and Harry (born 8th March 1899) arrived in Sydney on the Zealandia in June 1912. They had been in Quarriers Home in Bridge of Weir, Scotland for 2 years as their mother could not cope and then decided to try Australia. She was called Lizzie Norris. She was estranged from the father of the kids (John Pratt, stage name Nelldon).
I do not know if they changed their name when they reached Australia and it is one heck of a long shot but I wondered if anyone out their recognises the story.
thanks and regards
