New input case for you: Unable to secure the librarianship of the Bodleian whilst fellow, he had instead become tutor to his patron George Nugent-Temple-Grenville, 1st Marquess of Buckingham -- a position which he used to lead two of the Duke's sons and other members of the family to Brasenose; the sons' uncle, Baron Grenville, became the University's Chancellor. Under _his_ leadership into the early nineteenth century, numbers improved dramatically and so did the class of people coming: Brasenose began to be dominated by gentlemen like the Egertons, the Grenvilles, and of Richard Rainshaw Rothwell I. <sep>, Pronoun: his <sep>, A: Baron Grenville <sep>, B: Richard Rainshaw Rothwell I
Output:
A
