Notes and sources about HM Marines

What does '3rd Class' mean when referring to Marines?

What exactly is a Supernumerary?

Was there some specific mark to distinguish Chatham Marines from those of other Divisions? (Black plume in the De Loutherbourg painting - Bristol Art Gallery)

What, exactly, did the OR's lace look like?

What were the verbal orders given to a sentry? I'd like to know the form the orders took for a sentry post aboard ship - what the Marine was supposed to do. "To guard my position..." etc.

The duties and role of a boy, RM - still training? Able to do certain sentry duties? Officer's steward?

Drafts between divisions - how, why, how many.

Duties of women in the barracks? Since it was mentioned in the Records of the Marines thing

What does 'DSQ' mean in a man's records?

(This list just keeps on growing!! :D)

(I think this is possibly the best place to post this)

Questions to research/look into

1. Chatham Marines: Different plume? - possibly black according to some unsubstantiated sources.
2. The exact lace: white with one blue and one red stripe, yes, with the blue towards the outside edge. But was the red stripe in the centre, or towards the inside edge? Is there a sample from a sealed pattern or similar?
3. I'd like to know the form the orders took for a sentry post aboard ship - what the Marine was supposed to do. "To guard my position..." etc.
4. The nickname 'Jollies'. What are the origins of this name? (If they can be traced, that is.)

To be added to later...
