Mmm...as far as Vigilance is concerned, I know it's public knowledge that a sword-wielding elf wearing a death mask is Nyxvira's favorite enforcer and personal bounty killer. Only a few people would know Vigilance used to be Officer Narcissa Veclis of the SSPD. All files on the Great Fire of 1985 would probably mention Officers Veclis and Tavellan, Narcissa's lover at the time, died in the blaze. No bodies were found, though. I can't think of anything else involving Vigilance that would be public knowledge...
