Thanks Lucy2.
The problem here is that the lady concerned (who has been looked at here previously) was using a false name as far as we can tell. Her real name was Christiana I'Anson (nee Whitfield) but as her husband was on her trail to issue divorce proceedings against her new beau (who was finding his way to NZ separately via South Africa) she obviously tried to cover her tracks. She finally settled on the name Maydwell but that isn't the name she travelled under. It may have been a family name of Wilson but I suppose there are endless possibilities.
I'm thinking she may not have changed her children's first names as this would have been suspicious, but although they vanished from the family home six weeks after she left her husband, I have no real proof they all travelled with her, although they had apparently all arrived in NZ a couple of years later. Her youngest son Basil (who was registered in a Christchurch school in July 1905) obviously was with her I would say.
I've narrowed down a tiny window of travel, she will have left the UK sometime after the end of March 1905, and arrived in Christchurch by 3rd July.
She also had two older children who were not the children of her husband and they both eventually turned up with her too. Intriguingly, the daughter, Irene (who was legally Irene Whitfield) started using the new lover's surname of Oldbury. The older son travelled using the surname of I'Anson. Some of the others eventually took the name Maydwell.
