Why admiral names were unlikely for prewar heavy cruisers

Are the admiral names attached to unbuilt Royal Navy prewar heavy-cruiser designs supported by sources?

Probably not; Royal Navy practice makes county, town, Greek, or duke names more plausible for cruisers than admiral names.

Admiral names were more commonly reserved for capital ships, so their appearance on speculative prewar heavy-cruiser lists needs documentary support. The County class already established a strong cruiser naming pattern, while Town names and older Greek names offered familiar alternatives. Postwar use of HMS Blake does not prove that the unbuilt prewar ships would have followed the same convention. The admiral list is therefore doubtful, while a Duke class or another established cruiser series would be more credible.
