Pomerai or Pomeroy, of Berry-Pomeroy, in Devonshire, and of Tregony Castle, in Cornwall. This baronial family was seated at the former place in the reign of William the Conqueror. At an early period, one of their seats was at Tregony Castle, which continued to be the residence of the family in the reign of Edward IV. (fn. n2) The family do not appear to have been summoned to parliament as barons after the reign of Henry III. The Cornish branch of the Pomeroys became extinct in the reign of Queen Elizabeth, when the heiress is said to have married Penkevil.
