A letter to Cromwell in 1538 recounted the "cruell murdring of the Erle of Ormond's second son Thomas Butler." (see chronology below for full statement.) This event was witnessed by Thomas's brothers James and Richard, and James was also assaulted and "given dethly wounds by their own handes".
Unfounded rumours that became part of family lore claimed that Richard may have been the result of an affair between his mother Margaret Fitzgerald and Henry VII. It was noted that Margaret made every effort to advance her son Richard, but given her strength of character this was not unusual. The late 17th Viscount Mountgarrett (d. 2004) continued to claim descent from Henry VII. However, there is no relevant documentation in the public domain to support this claim.
Richard then was chosen in the entourage that went to Spain later that year to sign a marriage treaty and escort Prince Philip of Spain to England for his marriage to Queen Mary, and he and his nephew Ormond were rewarded with gifts on Philip's arrival.
The following entry is from “The Peerage of Ireland”, 1798, on the Mountgarrett Viscountcy:
(NB Fassaghbentry- refers to an area in the Barony of Bantry in Co. Wexford; Le-Moroes (MacMurrough-Kavanagh) country refers to the Barony of Scarawalsh, near the Blackstairs Mountains in Co. Wexford)
Viscount Mountgarrett's coat of arms is the same as the Ormonde arms with the addition of a crescent to denote the difference as the second son. They are displayed on the side of Richard 1st Viscount Mountgarrett's tomb in St Canice's Cathedral, Kilkenny.

Following the death of Richard’s brother James 9th Earl of Ormond in 1546 from food poisoning at a banquet in Holburn London, Richard became the defacto head of the Butlers during the minority of his brother’s heir young Thomas 10th Earl of Ormond who grew up at the court as the ward of King Henry VIII and as companion of Henry’s heir, the young Edward VI. Following the death of Edward in 1553, there was much dissension at the accession of the Catholic Queen Mary. Richard, as a Catholic appears to have found much favour in Mary’s Court. He played a prominent role in the quashing of the Wyatt Rebellion, an attempt to replace Mary with her young Protestant sister Elizabeth.
Feb 1554: The Calendar of State Papers Spain (Volume 12 Feb 1554 [pub.1949], p.86), reported:
1558: At the commencement of the reign of Queen Elizabeth we find the Viscount Mountgarrett applying to have “O’Morrowes lands in fee farm,” and to have some title of dignity, which will eclipse that of McMorrowe (Kavanagh), King of Leinster. He promises to build Castles etc.
On 8 October 1532, Ellen's father Theobald Butler wrote to the then Earl of Wiltshire and Ormond (Thomas Boleyn) :
Begs him to send his son James Butler to Ireland. Is sore punished by the earl of Ossory (Piers later 8th Earl of Ormond), so that he has lost his goods and is in "pinfold" in his castle of the Nezam and dare not come abroad. His kinsmen would fain have him out of the country but he trusts his Grace will redress everything. "My lord and his lady desired of me to make a 'tayll' and to put them and their heirs male before me and before my heirs male, and if I had done so they would give me my will and pleasure and I did forsake them of the same utterly." His cousin James (Piers' son and heir) is utterly against him and by his means the earl of Ossory has deprived him of four towns, leaving him only two villages and the twon he dwells in and he supposes the earl and James will have them soon. James says that he took of your Grace the Carryk by the water of the Showyr for a term of years at 10 marks the year and thinks to make it his own; asks Ormond to let him have it and he will pay 12."
(Letters and Papers Henry VIII Vol. 1, pt.1 ADDENDA, Vol. 22.1 (1509-1537), page 274/5 No. 793)
The above letter shows the toxic relationship between Piers Earl of Ossory and his son James towards Piers' nephew Theobald of Neigham, and their fear that they would lose their right to regain the Ormond Earldom if and when the Boleyns fell out of favour with Henry. This may have been the incentive for the marriage between Lord Mountgarrett and Theobald Butler's daughter Eleanor- a peace offering. The fact that second son Pierce married in 1563 would suggest that he was born in the late 1530's- early 1540's, which thereby contradicts the suggestion this marriage was Mountgarrett's first.
2. Catherine daughter and heir of Peter Barnewall of Stackallen Co Meath (Lodge Vol 2 p256)
Carew 635 calls her the sister of James Earl of Desmond. This is James the 13th Earl (see GEC).
