Baron Somers, of Evesham in the County of Worcester, is a title that has been created twice. The title was first created in the Peerage of England in 1697 for Sir John Somers, so that he could sit in the House of Lords and serve as Lord Chancellor. The title became extinct on Lord Somers' death in 1716. His sister and co-heiress, Mary Somers, married Charles Cocks, a member of a prominent Worcestershire family. Their grandson Charles Cocks represented Reigate in Parliament from 1747 to 1784, and was created a baronet, of Dumbleton in the County of Gloucester, in the Baronetage of Great Britain in 1772. In 1784 the barony held by his great-uncle was revived when he was made Baron Somers, of Evesham in the County of Worcester, in the Peerage of Great Britain.
His eldest son, the second Baron, sat as a Member of Parliament for West Looe, Grampound and Reigate and also served as Lord Lieutenant of Herefordshire. In 1821 he was created Viscount Eastnor, of Eastnor Castle in the County of Hereford, and Earl Somers. Both titles were in the Peerage of the United Kingdom. He was succeeded by his son, the second Earl. He represented Reigate and Hereford in the House of Commons and like his father served as Lord Lieutenant of Herefordshire. In 1841 Lord Somers assumed by Royal licence the additional surname of Somers. His son, the third Earl, sat as a Conservative Member of Parliament for Reigate.
