This is one of these bits of research that was going no where until one piece of information solved the whole problem.
These medals, both the main group and the miniatures came from RSL Care SA. Victor James Hopkins was born in Victoria in 1896. He served in WWI with the service number 4519. Victor was received a gunshot wound on 4 September 1918 and repatriated to Australia. This didn't stop Victor enlisting in WWII with the number VX18590. He did have to lie about his age to enlist.
There was limited information available on the public record about Victor's life. I had to make a couple of assumptions about him to narrow down the search possibilities until I could either prove or disprove those assumptions. For example, Victor named his father as his next of kin both times he enlisted. This suggested that he didn't marry. That was the start point of looking at the Birth, Death and Marriage records and marriage notices in news papers. I found no evidence he married. I found his father's death notice which only mentions Victor. This suggests he was an only child.
The search then began for the siblings of his parents. After a false start which took over a year to close off, I looked at his mother, Agnes McClure. I had to go back in history to her parents Ralph and Margaret McClure, and work out the names of any other children who were Agnes' siblings. This is the lead which led to success.
I've now been in contact with Annie who is descended from Ralph and Margaret and her family will become the custodian of Victor's medals.
The returned medal tally is now 2878.
