Baron Ellenborough, of Ellenborough in the County of Cumberland, is a title in the Peerage of the United Kingdom. It was created in 1802 for the lawyer, judge and politician Sir Edward Law, Lord Chief Justice of the King's Bench from 1802 to 1818. His son, the second Baron, notably served as Governor-General of India. In 1844 he was created Viscount Southam, of Southam in the County of Gloucester, and Earl of Ellenborough, in the County of Cumberland. These titles were also in the Peerage of the United Kingdom. His only son predeceased him and on his death in 1871 the viscountcy and earldom became extinct.
However, he was succeeded in the barony by his nephew, the third Baron. He was the son of the Hon. Charles Law, Member of Parliament for Cambridge University, second son of the first Baron. In 1885 he assumed by Royal licence the additional surname of Towry (which was that of his father's mother). On the death of his son, the fourth Baron, this line of the family failed. He was succeeded by his cousin, the fifth Baron. When he died the title passed to his younger brother, the sixth Baron. As of 2016[update] the title is held by the latter's great-grandson, the ninth Baron, who succeeded his father in 2013.
