Regional backgrounds among British admirals

Where in Britain and the Commonwealth did admirals and generals tend to come from?

They came from across Britain and sometimes the Commonwealth, with a strong western-British presence among Royal Navy admirals in this informal assessment.

The senior Royal Navy appears geographically mixed rather than drawn from one formal recruiting region. The answer nevertheless notes a concentration of officers from western Britain, especially the southwest and northwest, alongside officers from Scotland, Wales, the Midlands, and the southeast. Commonwealth officers from Australia and Canada also appear among senior ranks, particularly before the postwar period. This is an impression of naval leadership's social geography rather than a statistical survey.
