A commoner who holds the lowest hereditary title of honour (7)

Ross

I believe the answer is:

baronet

(Other definitions for baronet that I've seen before include "A Bronte (anag.)" , "Minor title" , "A Breton could be a British peer" , "Nobleman" , "Titled man" .)

I've seen this clue in The Independent.
