Grubb family
From Tolkien Gateway
The Grubb Family was an important and wealthy family of the Shire-hobbits. At least some of the family were involved in auctioneering, a fact we can deduce from the name of the company set to sell Bilbo's belongings at the end of The Hobbit, Messrs. Grubb, Grubb and Burrowes. In fact, Bilbo had a slight connection with the family: his paternal grandmother was Laura Grubb. She married Mungo Baggins, and together they produced five children, of whom the eldest was Bungo Baggins, Bilbo's father.
