The Victory Medal awarded to 6/2124 Crawford Ernest Eyes NZEF, came to me from the collection of Diane F. My starting point when researching Crawford was the Auckland War Memorial Museum. This gave me the lead on the family and I soon discovered Crawford's brother William moved to Australia. A series of post of some family history websites lead me to William's grandson Peter, who lives in Melbourne.
Thanks to all the information that has been posted on the web about this family, the search only took about an hour. The returned medal tally is now 983.
