Of Word Origins and Anachronistic Phraseology

We've been hunkered in the Write and Polish bunker for the last couple of weeks, working away furiously. We hope to have something to show (publicly) for it soon. 

But, in the meanwhile, we submit for your entertainment and edification this mash-up of Downton Abbey linguistic anachronisms 
(NOTE: spoilers for season 2).

Though we are persuaded by most of the explanations as to the origins and documentable first-uses, slang always occurs in speech before finding its way into the written record. So, one or two of these phrases might be less anachronistic than they first appear.
