Although I have my grandfathers medals I decided to get copies of the medal cards to add to my records. Interestingly, when I downloaded the cards from the National Archives website, there were 6 of them. Careful examination led me to conclude that 5 were for other William Hodgsons, the 6th card was an exact match with the details engraved on the medals and the information in his war records. I think this shows that you cannot draw conclusions from the medal cards alone and need further supporting evidence to prove that the cards relate to the serviceman that you are researching.
