Can any person in the US be granted a title of nobility?

There is no authority granted by the constitution that gives power to the US to grant any title of nobility to anyone.

Article 1 section 9 states... No Title of Nobility shall be granted by the United States; and no Person holding any Office of Profit or Trust under them, shall, without the Consent of the Congress, accept of any present, Emolument, Office, or Title, of any kind whatever, from any King, Prince, or foreign State.
