Blog labelling convention

Probably time the label naming convention being used here was re-stated.

• SURNAMEs mentioned are shown in capitals
• Places usually have a higher order place (in brackets) after them, usually using Chapman codes or the abbreviated county/country list that used to be distributed with the GRD

Anything else is just a key word of some sort, or a place that hasn't yet been supplemented by a (CODE), of which latter there will be a few still.
