When did Marquis of Verboom die?

There is no historical record of a Marquis of Verboom. It's possible you're thinking of a different title or a misspelling. Could you please provide more information?

For example:

* Is it a fictional character? If so, from what book or movie?

* Is it a real person but with a slightly different name?

* Do you know any other details about this person? For example, their profession, nationality, or approximate date of birth?

With more information, I can help you find the answer.
