      RESIDENCE: Raglan Castle. (Bradney, History of Monmouthshire, vol. 1 p. 31)
      RESIDENCE: Raglana. (Jones, History of The County of Brecknock, vol. 2 pt. 2 p. 250)

      PROPERTY: Lord of Raglan.
      PROPERTY: He held 'Llantilio Regis' under the Crown as of the lordship of Whitecastle, while he held 'Llantilio Episcopi' by lease from the Bishops of Llandaf. (Bradney, History of Monmouthshire, vol. 1 p. 93)

There are three accounts of its prime ancester. 1) the race springs from Herbert, a natural son of Henry I of England (this version has never met with acceptance), 2) gives Henry Fitz Herbert, Chamberlain to Henry I as prime ancestor, 3) Henry Fitz Herbert, the Chamberlain was son of Herbert, son of Godwin, son of Elfryd, and that the said Herbert married the daughter of Godwin, Earl of Kent."
