Thank you spades,
I am sure that the administrators haven’t investigated some of the suggestions that you have made, so will pass this information on to them. From what I understand the names of the parents who went to NZ are known and possibly some of their children, but these would be grown up now and may or may not still be alive. Then of course, they may have had children who need tracing. I am just glad I am not doing the searching!
Cheers,
