Military Rank: Colonel, General, Major, Admiral, Captain, etc; all these and whatever else could be bestowed upon the Inquisitor as a title owing to a previous career, an honorific granted by a particular institution or simply be of their own devising (and dreams of military glory?).

11-30

Ordo-specific: Something related to the Inquisitor's line of work, e.g. an Ordo Hereticus Inquisitor might be Witch-Finder, Witch-Hunter, Colonel-of-Redemption, etc.

31-40

Facility title: Steward, Custodian, Administrator, Governor and Castellan are all titles an Inquisitor may possess if they are in charge of a particular facility, ideal for Inquisitors Historical or Theoretical that spend a lot of time in research archives at Inquisitorial strongholds, 'holding down the fort'.

41-60

Nobility: Sir, Lord, Duke, Count, Boyar, Fürst, Emir, Sheikh, etc. are all titles that could be held in the Imperium, showing the Inquisitor has either come from a noble line, could have been awarded it or has simply usurped it from a previous (no doubt heretical and deceased) holder.

61-70

Miscellaneous: This could be pretty much anything, as in nicknames or popular names granted by compatriots or enemies, and so are usually informalities left out of official documentation. Examples include Psykerbane, Lucky, Warhound, Thrice-Blessed or names ending in the end (such as the Invincible, the Pure, the Cursed, etc). Can be both before or after the real name, for example Lucky Jack and Ekene One-Eye.

71-100

Nothing: The Inquisitor's only title is that, which should be scary enough!
