Baron Sheffield is a title that has been created four times: once in the Peerage of England, twice in the Peerage of Ireland, and once in the Peerage of the United Kingdom. The first creation, as Baron Sheffield of Butterwick, was in the Peerage of England in 1547 for Edmund Sheffield, second cousin of Henry VIII, who was murdered in Norwich during Kett's Rebellion. His grandson, the 3rd Baron Sheffield, was created Earl of Mulgrave in 1626, and the 3rd Earl of Mulgrave was finally advanced to the dukedom of Buckingham and Normanby. At the death of the 2nd Duke of Buckingham and Normanby, however, all of the titles became extinct since no heirs to them remained. The next three creations were all in favour of one person, John Baker-Holroyd. In 1781, on the second creation of the title, he was made Baron Sheffield, of Dunnamore in the County of Meath in the Peerage of Ireland. This peerage was created with normal remainder to the heirs male of his body. Two years later, in 1783, John Baker-Holroyd obtained the third creation of the title when he was made Baron Sheffield, of Roscommon in the County of Roscommon, also in the Peerage of Ireland, with remainder, failing heirs male of his body, to the heirs male of his daughters from his first marriage. On the fourth creation of a Sheffield barony in 1802, John Baker-Holroyd was created Baron Sheffield, of Sheffield in the County of York, in the Peerage of the United Kingdom. In 1816 the same John Baker-Holroyd was further made Earl of Sheffield and Viscount Pevensey in the Peerage of Ireland. The latter titles were all created with remainder to the heirs male of his body. He was succeeded by his son from his second marriage. On the death in 1909 of the 3rd Earl of Sheffield, his earldom, the Pevensey viscountcy and the Sheffield baronies of 1781 and 1802 became extinct. However, he was succeeded in the Sheffield barony of 1783 according to special remainder by Edward Stanley, 4th Baron Stanley of Alderley, who was also 3rd Baron Eddisbury and now became 4th Baron Sheffield as well. The 4th Baron Sheffield was the grandson of Lady Maria Josepha Holroyd, daughter of the 1st Earl of Sheffield. These titles remain extant and united, see Baron Stanley of Alderley for further succession.
