All you had to do was to look at the reference section.  Next to the Club Claims reference is stated the following: The Copley family listed as claimants: claim numbers 726 - 722.  It lists the names of the entire Copley family mentioned in the article and groups them together as claimants.  This is further proof of their family connection.  It would be virtually impossible for random unrelated Copley's to have joined with consecutive member numbers.
