The title Earl of Montgomery (pronounced "Mun-gum-ery") was created in the Peerage of England in 1605 for Sir Philip Herbert, younger son of the 2nd Earl of Pembroke. The first Earl inherited the Earldom of Pembroke in 1630 from his brother, the 3rd Earl, and the two titles remain united.[2]

The heir apparent is the present holder's only son Reginald Henry Michael Herbert, Lord Herbert (b. 2012).
