Catalogue description THADEUS O'BYRNE.

Indenture made 22nd January 1535, 28 [Sic. Mistake for 27.] Hen. VIII., between Lord Leonard Grey, Justiciary of Ireland, and Thadeus O'Byrne, principal captain of his nation. By the arbitration of the Earl of Ossory, William Brabazon, the King's Treasurer of War in Ireland, Gerald Aylmer, Chief Justice of the Chief Bench, and Edmond Juvenis O'Birne, it was concluded between the said Justiciary and the said O'Birne as follows:

(1.) O'Birne will be faithful and obedient to the King, will keep firm peace with all the King's subjects, permit them quietly to go and return through his country, and not allow any enemy of the King to come through his dominion to invade them. He will not adhere to any Irishman or any other against the King or his subjects, or maintain any enemy or rebel of the King, especially those of the nation of O'Tholis, fleeing into his country.

(2.) Whenever the Justiciary or Deputy shall make a hosting against any rebels in any part outside Leinster, O'Byrne will send a banner with twenty horsemen, "cum numero pedestrium seu turbiculorum tot equestribus," according to the custom of his country, at his own expenses. If within Leinster, O'Birne will rise up with all his force.

(3.) He will deliver and pay to the Deputy 120 cows or martes this side the feast of St. Philip and St. James next.

(4.) In case of necessity O'Birne and his country will succour and support the Deputy with 120 armed footmen, Irish, Scotch, or galloglaghes, for four, six, or eight weeks, or a quarter of a year, if need be.

(5.) He will exonerate Hugh Nugent, John Beling, James Rychford and all others from all arrears and debts not yet paid for their ransom, and deliver the pledges of Nugent and Beling remaining with the Prior of the Holy Trinity, Dublin, and the Abbot of St. Mary's near Dublin, for the remainder of their ransom.

(6.) For the observance of the premises the Earl of Ossory and Edmond Juvenis O'Birne will deliver the castle of Symons Wodde to the Lord Justiciary or Deputy for the time being.

(7.) Declaration to be made when necessity arises for supporting the said 120 footmen, by the Lord Justice of Ireland for the time being and the Lord Archbishop of Dublin, or in his place the Chancellor.
