Not currently, though you can skim some of the opening bits and bobs in various books - I thought Run Faster had a 'all these guys bought the farm only last month' or something, but it wasn't that.
Unless they're especially significant (e.g. The Big D, Fastjack, Captain Chaos, Hatchetman), you can always drop a name or three, see if they notice. And in general, you don't have to absolutely keep to canon, eh? 'The rumors of my demise are greatly exaggerated,' and all.
