Baron La Poer

The progenitor of the family was a companion of Strongbow, from whom he obtained grant for extensive lands in Waterford c. 1172.[1] The barony was created in 1535 for Sir Richard le Poer.[2]

James Power, 3rd Earl of Tyrone, who was also the 8th Baron Power, held both his titles by letters patent (dated 1535 and 1637 respectively), which specified that the titles would be inherited by heirs male of the grantee. When he died in 1704 however, his only child was a daughter, Lady Catharine Power. The Earldom became extinct, and in an ordinary course of events, the Barony of Power would have been inherited by his distant cousin, Colonel John Power (or Poore) of the French Régiment de Dublin. The colonel was however a Jacobite and therefore outlawed and attainted in 1688. Although inheriting none of the titles, Lady Catharine therefore inherited the land.

Lady Catharine grew up and married in 1717 an Irish politician, Sir Marcus Beresford, 4th Baronet.[3] After a lawsuit with John Power, Sir Marcus and Lady Catharine retained the Power property, and Sir Marcus was raised into the Peerage of Ireland by creating him Viscount Tyrone in 1720. After the Jacobite rebellion of 1745, he was further elevated in 1746 as Earl of Tyrone (the same name of title as that of his father-in-law, but a new creation). After he died in 1763, Lady Catharine, now the Dowager Countess of Tyrone, had petitioned the Irish House of Lords to restore to her the "Barony de la Poer", which she asserted was created by writ for her grandfather Richard Power.[3] He was summoned to the Parliament of Ireland somewhere in the 1650s, but was not yet a peer. He became the 6th Baron Power in 1661, and was created the 1st Earl of Tyrone and 1st Viscount Decies in 1673.

Instead of a barony by patent, a "barony by writ" is a hereditary title created by a writ of summons, but without issuing a letters patent. Other differences are that a barony by writ is inherited in strict order of succession by the heirs general of the recipient of the writ: daughters of barons, if they are only children (like Countess Catharine), do therefore inherit such baronies. A barony by writ is a typical creation of English common law, but aside from this case, they are now almost non-existent in the Peerage of Ireland.

Both titles and the surnames le Poer and Power are all forms of the same name, originally Anglo-Norman le pover, meaning "the Poor" (i.e. poor man). The sobriquet specifically referred to a vow of poverty undertaken by religious men rather than ordinary poverty. It was quite common in medieval England and Ireland.[4] Romantics have also claimed a connection with Poher in Brittany.[5]

The spellings de la Poer and La Poer, in the feminine, originate from the Countess's petition, although it is ungrammatical, and J. H. Round called it "idiotic";[6] the feminine article may be the result of applying it to a peeress. Her spelling has been widely used as a middle name by her Beresford descendants; some of the Powers also adopted this fashionable spelling.
