Did they have a daughter called Lilian Mona Corrin born in the Isle of Man in 1914? Did Jack go to New Zealand in 1913 and Laura and Lilian in 1914? There are passenger lists on Family Search for a John Corrin arriving in New Zealand on the ship Mamari on 30 December 1913 and for a Mrs Corrin and an infant child called L Corrin arriving in New Zealand on the ship Mamari on 7 December 1914. I can post links to these passenger records if it is them.
