Baron Langford, of Summerhill in the County of Meath, is a title in the Peerage of Ireland. It was created on 1 July 1800 for Clotworthy Rowley, who had earlier represented Trim and County Meath in the Irish House of Commons. Born Clotworthy Taylor, he was the fourth son of Thomas Taylor, 1st Earl of Bective and Jane Rowley, daughter of Hercules Langford Rowley and his wife Elizabeth Rowley, 1st Viscountess Langford. The viscountcy of Langford became extinct in 1796 on the death of Hercules Rowley, 2nd Viscount Langford. Clotworthy Taylor succeeded to the Rowley estates and assumed by Royal licence the surname of Rowley in lieu of Taylor. Four years later the Langford title was revived when he was raised to the Peerage of Ireland as Baron Langford.
