Baron Dormer, of Wyng (or Wenge), County of Buckingham, is a title in the Peerage of England.
He had, only twenty days earlier on 10 June 1615, been created a baronet "of Wing in the County of Buckingham", in the Baronetage of England.
His grandson, the 2nd Baron Dormer was raised to Viscount Ascott in the County of Buckingham, and Earl of Carnarvon in 1628, and later became a prominent Royalist commander in the Civil War.
However, the late Earl was succeeded in the baronetcy and barony by his second cousin, the fourth Baron.
His grandson, the tenth Baron, who succeeded his half-brother in 1819, was, like many of the recusant Dormer family, a Roman Catholic.
