Page "Duke of Buckingham and Normanby" Paragraph 2

The duke's family descended from Sir Edmund Sheffield, second cousin of Henry VIII, who in 1547 was raised to the Peerage of England as Baron Sheffield and in 1549 was murdered in the streets of Norwich during Kett's Rebellion.

His grandson, the 3rd Baron, served as Lord Lieutenant of Yorkshire from 1603 to 1619 and was created Earl of Mulgrave in 1626, also in the Peerage of England.

On the death of the 2nd Duke of Buckingham and Normanby in 1735, all these titles became extinct.

The Sheffield family estates passed to the 2nd Duke's half-brother Charles Herbert Sheffield, the illegitimate son of the 1st Duke by Frances Stewart.

He was created a Baronet in 1755 and is the ancestor of the Sheffield Baronets, of Normanby.
