I use this table to generate all of my mercenary and henchmen names. The names generated not only fit the setting but add additional depth. I haven't tried to use it on the fly during a game but I imagine it would work for that as well.

A nifty little name list/generator specifically for AS&SH that is also a goldmine for other game systems. The names range from historically plausible (Jofursteinn Manason - Viking) to exotically fantastic (Goozon Slann - Hyperborean). I recommend checking out AS&SH for its 30's pulp atmosphere, but even if you don't, the price of $0 for this name generator leaves you no excuses: Just download it!
