The 1876 Ordnance Survey map refers to the road as "Shelburne" Road, a spelling that conforms to that of one of the titles of William Petty-Fitzmaurice, Marquess of Lansdowne, second Earl of Shelburne (family name Petty-FitzMaurice). Petty-Fitzmaurice, born in Dublin, was Prime Minister from 1782 to 1783. It is unclear how the spelling of today's Shelbourne Road acquired an "o"; Shelburne Falls in Massachusetts, also named in commemoration of William Petty-Fitzmaurice, has conserved the original spelling.
