Thanks so much for your full, thoughtful and helpful reply.
Its so refreshing to have someone give such good advice.
I will follow up asap.
I found this on the web today.http://www.network54.com/Forum/47207/thread/1084682372/Tiger...
It refers to Ewald Kruska and has the NZ connection.
I can send you a scan of the document I have - its a passport type document BUT it his Army papers with photo and qualifications.
It is written in Sütterlin so there are few who can help with the translation.
I am trying to determine the birth place from the papers and it looks like Munchen but I need help. I was then to try and get his parents names and then trace down that line.
I can email the scans to you if you can assist.
My email address is ........ and if you email me I can send them to you.
Thanks so much
