Thomas mac Edmond Albanach de Burca

A son of Sir Edmond Albanach de Burgh and Sadhbh Ni Maillie (daughter of Diarmuid mac Owen Ó Máille), de Burca succeeded his father in 1375. He died in 1402, and was succeeded by Walter mac Thomas de Burca. He had issue:

• 1 - Meyler, died 1384.
• 2 - David, died 1384.
• 3 - John, died 1384.

• 5 - Edmond, died 1458.
• 6 - Thomas, died 1460.

From his son, Walter, descended almost all subsequent Mac William Iochtar's and their successors.

From the Annals of the Four Masters:

• M1377.5. Rory O'Conor defeated Mac William Burke, and Melaghlin O'Kelly, Lord of Hy-Many, at Roscommon, where Richard Burke, the brother of Mac William, Donnell, the son of Cathal Oge O'Conor, Teige Oge, the son of Teige O'Kelly, O'Mainnin, Chief of Sodan, Mac Dowell Galloglagh, and many other persons not enumerated, were slain.
• M1380.3. Mac William Burke defeated Mac William Uachtrach (Richard Oge) at the town of Atha-leathann (Strade), where Mac Jordan de Exeter, Lord of Athleathan, and John de Exeter, were slain.
• M1384.13. Meyler, son of Sir William Burke, was killed by a fall. John and David, two other sons of Mac William Burke, died of the plague.
• M1385.8. Tireragh was burned by Mac William Burke; he afterwards went to Sligo, which was burned by him in like manner, together with South Carbury. But here battle was given to him, and Maidiuc Mael, one of the chiefs of his people, was slain; and hostages were afterwards forced from him.
• M1386.7. O'Conor Roe, with all the Connacians he could find to join him, went to assist Mac William Burke against Donnell, the son of Murtough O'Conor Sligo, and the Clann-Donough. They carried off great preys from Tir-Fiachrach Muaidhe. After this they proceeded to Clanrickard on a predatory excursion. O'Brien, with a great army, and Mac William of Clanrickard, came up with them; but O'Conor Roe turned round on them, and defeated them; and Conor, the son of Teige, son of Conor O'Brien, was slain in the conflict.
• M1386.11. A peace was made by the Connacians with one another after the war, and Mac William Burke went into the house of Mac William of Clanrickard, and ceded to him the lordship. Mac Feorais Bermingham went into his house in like manner.

An army was led by Donnell, the son of Murtough O'Conor, and the Irish of Lower Connaught, into Mac William's territory, in consequence of the capture of Mac Jordan; and Mac Jordan was liberated, and peace was ratified between the English and Irish of the province on this occasion.
• M1398.4. An army was led by Thomas Burke, Lord of the English of Connaught, and by O'Conor Roe and the sons of Cathal Oge, into Tirerrill, which they entirely plundered.

After the death of this Thomas Burke, two Mac Williams were made, namely, Ulick, the son of Richard Oge, who was elected the Mac William; and Walter, the son of Thomas, who was made another Mac William, but yielded submission to Mac William of Clanrickard for his seniority.
