[1] Murrough: This Murrough O'Brien, having, A.D. 1543, dispossessed his nephew, Donogh, of the principality of Thomond, repaired to England and made his submission to King Henry VIII., to whom he resigned the principality, and was created therefor "Earl of Thomond," and Baron of Inchiquin: the conditions being, that he should utterly forsake and give up the name O'Brien, and all claims to which he might pretend by the same; and take such name as the king should please to give him; and he and his heirs and the inheritors of his lands should use the English dress, customs, manners, and language; that he should give up the Irish dress, customs, and language, and keep no kerns or gallowglasses.—CONNELLAN.

[2] Toitean: Murrough-an-Toitean ("toitean:" Irish, a burning, or conflagration) or Murrough of the Conflagrations, was appointed President of Munster, where he is well remembered for his cruelties, and always mentioned with an imprecation; so cruel that in Munster it is commonly said of a person who appears to be frightened; Do chonnairc se Murcadh no an tur b-fhoisge do, "He has seen Murrough or the clump next to him." This Murrough, in 1642, at the head of 1,850 foot and 400 horse, attacked the Irish under Lord Mountgarret, at Liscarroll, and defeated them with great slaughter. He sided with the Parliament, in 1644, against King Charles the First, and was by that Parliament appointed President of Munster. In 1647, he reduced several fortified places in the county of Waterford; besieged Cahir, in Tipperary, which surrendered to him; and took "Cashel of the Kings" by storm:

"The inhabitants of Cashel," says Lewis, "took refuge in their church on the rock which was well fortified and garrisoned. Inchiquin proposed to leave them unmolested on condition of their contributing £3,000, and a month's pay for his army. This offer being rejected, he took the place by storm, with great slaughter, both of soldiers and citizens: among them twenty of the clergy were involved; and, having secured the immense booty of which he obtained possession, he dispersed his forces into garrison."

Murrough-an-Toitean defeated the Irish under Lord Taaffe and Sir Alexander MacDonnell (commonly called "Alastrum Mór," who was the eldest son of Sir James, of Eanagh and Ballybannagh, No. 118 on the "MacDonnell," of the County Clare pedigree), at the Battle of Knocknaness, on the 13th of November, 1647; for which the Parliament sent him a letter of thanks, with a present of £1,000. In 1648, he reduced Nenagh, as appears by the following letter which he wrote to his friend, Colonel David Crosbie, Governor of Kerry:

"I have reduced Nenagh, and am this day marching after Owen Roe (O'Neill), either to the Boyne or Borris-in-Leix. Preston is before Athy, and being possessed of part of it three days since, it is confidently believed he is Mr. (Master) of it by this tyme. I have now only to advise you to use your best care in keeping ye country in good order, remayneing

"Yor affectionate friend,



17th Sept., 1648."

Of Murrough-an-Toitean we read in De Vere's Wail of Thomond:

"Can it be? Can it be? Can O'Brien be traitor?

Can the great House Dalcassian be faithless to Eire?

The sons of the stranger have wrong'd—let them hate her!

Old Thomond well knows them; they hate her for hire!

Can our Murrough be leagued with the rebels and ranters

'Gainst his faith and his country, his king and his race?

Can he bear the low wailings, the curses, the banters?

There's a scourge worse than these—the applause of the base!

"Was the hand that set fire to the churches descended

From the band of the King that uprear'd them, BOROIMHE?

When the blood of the priests and the people ran blended,

Who was it cried, 'Spare them not?' Inchiquin, who?

Some Fury o'er-ruled thee! some root hast thou eaten!

Twas a demon that stalked in thy shape! 'Twas not thou!

Oh, Murrogh! not tears of the angels can sweeten

That blood-stain; that Cain-mark erase from thy brow!"

Soon after the reduction of Nenagh, Murrough-an-Toitean changed sides: Early in 1649, he openly espoused the cause of Charles II., who in a letter from the Hague appointed Murrough President of Munster; and on the 14th of April of same year he was pronounced a traitor by the Commonwealth Parliament. On the 1st of June following he sent the subjoined communication:

"To the Officer commanding in Cheeffe, Castlemaine.

By the Lord President of Maunster:

"You, and the rest of the Warders of Castlemaine, are hereby required to be obedient to the directions and commands of Coll. David Crosbie uppon all occasions, and to deliver him, if occasion shall require for his Maties. (Majesty's) service, admonition (ammunition) out of the said Castle; thereof you may not faile at yor pill (peril); and for yor soe doeing this shall be yor Warrant.


"Dated the first of June, 1649."

My Lady of the Chimney CornerMy Lady of the Chimney Corner

A memorable and moving story of the triumph of the human spirit in the face of adversity. In 1863 the author, Alexander Irvine, was born into dire poverty, the child of a 'mixed' marriage. His parents had survived the ravages of the famine years, but want and hunger were never to be too far away from their door. Irvine was ultimately destined to leave Ireland for America and to become a successful minister and author. He learned to read and write when he had left his home in Antrim far behind, but he came to realize that the greatest lessons he had received in life were at his mother's knee. My Lady of the Chimney Corner is the depiction of an existence that would be unthinkable in modern Ireland; but, more than that, it is the author's loving tribute to his mother, Anna, who taught him to look at the world through clean spectacles. ISBN 978-1-910375-32-7. USA orders. The book is also available as a Kindle download (UK) and Kindle download (US).

Annals of the Famine in Ireland

Annals of the Famine in Ireland

Annals of the Famine in Ireland, by Asenath Nicholson, still has the power to shock and sadden even though the events described are ever-receding further into the past. When you read, for example, of the poor widowed mother who was caught trying to salvage a few potatoes from her landlord’s field, and what the magistrate discovered in the pot in her cabin, you cannot help but be appalled and distressed.

Ireland's Welcome to the Stranger

Ireland’s Welcome to the Stranger

This book, the prequel to Annals of the Famine in Ireland cannot be recommended highly enough to those interested in Irish social history. The author, Mrs Asenath Nicholson, travelled from her native America to assess the condition of the poor in Ireland during the mid 1840s. Refusing the luxury of hotels and first class travel, she stayed at a variety of lodging-houses, and even in the crude cabins of the very poorest. Not to be missed!
