Clancy
Clancy (i) - daughter of War
Clancy is War's daughter, appears in Interesting Times, and is portrayed as a spoiled little girl wearing a Pony Club hat. As the daughter of a Valkyrie, this is perhaps only fitting. She has a permanent scowl which makes her brothers Panic and Terror somewhat redundant at the moment.
Annotation
Clancy's description evokes the work of British cartoonist Norman Thelwell[1], who specialised in drawing cartoons of serious, somewhat grumpy, Pony Club girls and their ponies, described as "fat little things with a leg at each corner" (a description used somewhat ambiguously - it isn't clear that this is just about the ponies). Thelwell's cartoons[2] tend to depict mini-Valkyries getting into all sorts of equine scrapes, and there was a big vogue for them, among the horsy set, in the fifties and sixties.
Clancy (ii) - the butchers
Sidney Clancy (39) and Son, 11 Long Hogmeat, Purveyors of Finest Cat and Dog Meats To The Gentry.
Vetinari's pet-food retailer of choice for Wuffles and a lifesaver for Otto Chriek. However, there is a hint in Making Money that with the advent of a new pet dog, Clancy's may have lost the contract to a new supplier.
Clancy (iii) - XXXX'ian
This Clancy is a stock man who works for Remorse in The Last Continent, and helps invent XXXX-ian slang. Well, he is frequently accused of inventing it and winging it when he doesn't know the correct slang term
