Baron Sudeley is a title that has been created thrice in British history, twice in the Peerage of England and once in the Peerage of the United Kingdom. The first creation came in the Peerage of England in 1299 when John de Sudeley was summoned to Parliament as Lord Sudeley. On the death of the third Baron in 1367 the title fell into abeyance. The abeyance was terminated in 1380 when Thomas Boteler, the fourth Baron, became sole heir. The sixth Baron was created Baron Sudeley by letters patent in 1441. He served as Lord High Treasurer from 1444 to 1447. On his death in 1473 the 1441 creation became extinct while the 1299 creation once again fell into abeyance.
The third creation came in the Peerage of the United Kingdom in 1838 when Charles Hanbury-Tracy was created Baron Sudeley, of Toddington in the County of Gloucester. He had previously represented Tewkesbury in the House of Commons as a Whig and served as Lord Lieutenant of Montgomeryshire. He was also as Chairman of the Royal Commission appointed to judge designs for the new Houses of Parliament. He married his cousin Hon. Henrietta Susanna, daughter and heiress of Henry Leigh Tracy, 8th and last Viscount Tracy, through which marriage the estate of Toddington Manor in Gloucestershire came into the Hanbury family. Five days before the marriage Charles Hanbury assumed the additional surname of Tracy.
