Web Notes notes for Sir Daniel O'BRIEN 1st Viscount Clare
He also had seven daughters.

From the book, "O'Brien of Thomond,"
p.23: Daniel was created First Viscount of Clare by King Charles II in 1662. He had an active and perilous life.
p.34: As revolt spread across the country, the O'Briens were divided. The Earl of Thomond and his brother Daniel supported the Queen. About 1599, Daniel was assaulted in Kilmurry Castle, Ibrickan by Tiege MacMahon. He was wounded and taken prisoner a week at Doonbeg.
p.35: Carrigaholt became the home of Daniel and his successors for the next century. It and other properties were granted to him by the queen in a letter of "Manor of Greenwich, July 8th 1601."
p.36: His brother, Earl of Thomond went to England and took Daniel with him. This was the start of Daniel's court career. His loyalty to the monarch earned him a viscountancy 60 years later, but it also brought his great-grandsons to disaster and permanent exile from the British Isles 90 years later.
p.49: Daniel lived till after the Restoration.
p. 59: He was a Member of Parliament.
p. 67: In 1642, Daniel began attacking the Protestants of Co Clare. He began to seize arms and cattle
p. 68: A well-authenticated attack was the siege of Ballyallia Castle in 1642. Attackers were led by Sir Daniel O'Brien, Colonel Conor, and the O'Brien brothers from Dromore. The castle was occupied by Marice Cuffe, a Protestant merchant of Ennis. Starvation forced capitulation after a siege of some months, but Cuffe escaped to Bunratty and wrote a detailed account of events.
p.81: In 1652, Sir Daniel O'Brien joined Lord Muskerry after the seizure of his own Carrigaholt Castle in Nov 1651. Sir Daniel and Muskerry's son were made to stand hostage for the performance of the terms of surrender. After, Sir Daniel was allowed to retire to the continent and join King Charles II in exile.
p.85: The title of Viscount Clare was awarded to Sir Daniel soon after the Restoration. At the time of his going into exile, he was past 70 and too old for active service. His descendants, the 3rd and 4th Viscounts, were also to flee into exile at a later date.
p.95: The Restoration in May 1660 of King Charles II brought most of the O'Briens in exile back to Ireland and their estate. Sir Daniel received his peerage in 1662. He was created Viscount O'Brien of Clare but he and his successors have been known as Lords Clare to distinguish them from the Lords O'Brien, eldest sons of the Earls of Inchiquin.

According to the book, O'Brien of Thomond, he died in 1663.

According to Burke's Landed Gentry, 1912, p229 footnote, he was the son of Catharine, daughter of Gerald FitzGerald, 15th Earl of Desmond, the Rebel Earl, who was attainted 15 Nov 1582, when his vast estates, the largest in Ireland, were forfeited. Daniel, 3rd Viscount Clare, was attainted 1691. The Viscounty of Clare became extinct with the Earldom of Thomond 29 Dec 1774.
