Whitlocke or Whitlock?

By ThenDoctor, in Dark Heresy

Was there ever confirmation that Inquisitor Whitlocke (described in the initial example of play in DH1's core) is Inquisitor Whitlock (the one all about halo devices) and it was just a typo?

I'm assuming yes, as there are a few other examples of similar minor name changes as well.

Or was Whitlocke was ever mentioned elsewhere in the books ever.
