BP1934 (De La Poer) starts its article with "The family of Power, originally de Poher, Le Poer, and de la Poer, was founded in Ireland by Sir Robert de Poher, Knt., Governor of Waterford 1177, one of the companions of Strongbow". BE1883 starts its article with "Sir Roger de la Poer, Knt., who accompanied Strongbow into Ireland ...". We presume that Sir Roger was the same person as Sir Robert.

  (i) David Poer (a 1375)
BP1934 reports that David was summoned to Parliament in 1375, etc., whilst BE1883, which starts with his son Nicholas, reports that it was son who was so summoned. As reported below, TCP (Power) indicates that neither were.

  (a) Nicholas Poer, Sheriff of co. Waterford (a 1424)

(1) BE1883 reports that Richard was created Baron of Curraghmore and that his grandson Richard was re-created the same. TCP (Power) reports that "This Richard is sometimes (but erroneously) said to have been cr. by Henry VI in 1452 "Lord Le Poer, Baron of Curraghmore," through confusion with his grandson Richard."
(2) BE1883 suggests that Richard's wife was daughter of "Sir Richard Butler, Earl of Ormonde" but, noting that there was no such earl, we follow BP1934 in identifying her as ...

  m. Katherine Butler (dau of Walter Butler, 11th Earl of Ormonde)
  a. Piers Power of Monalargie
  Piers supported the rebellion of 1641 and was attainted. As a result, his descendants' claim to the barony was not formally accepted although it appears that his son and grandson were often styled as barons.

  m. Elenor Power (dau of Piers Power of Monalargie) @1@ above
  (A) John Power of Grange, '11th Lord' (d 05.1743)
  TCP suggests that the titles, not formally accepted because of the attainder, were not used by John and his successors. We continue to show how the title would have passed not least because this is shown in BP1934 whilst TCP continues to show the line of descent.

  (i) Catherine Power
  m. John Power of Clashmore
