A little-known family of Shire-hobbits, of which Robin Smallburrow is the only named member. The family is circumstantially connected to the Eastfarthing of the Shire (as suggested by the fact that Robin Smallburrow, as a member of the First Eastfarthing Troop, was stationed at the Brandywine Bridge, though of course this is by no means conclusive). The 'burrow' of the name is presumably a reference to a Hobbit-hole, suggesting that (at least at some point in the past) this was a relatively poor family with only a minor smial to its name.
