Walter de Burgh, Baron of Connaught
Walter de Burgh, Baron of Connaught (21) (about 1230 - 1271), Earl of Ulster and Constable of Ireland. He married Maude de Lacie (21) who died 1303 (she was the daughter of Hugh de Lacie, Earl of Ulster (22) and Constable of Ireland. Sir Hugh came to Ireland in 1171, was Lord Palatine and a descendant of Charlemagne.)
Their son was Richard de Burgh, 2nd Earl of Ulster (20) (1259-1326), Lord Justice of Ireland in 1296.
His father was Richard Mor de Burgh the Great (22) (? - 1243), Lord of Connaught and Trym, Lord-Lieutenant of Ireland 1227.
[ It looks like there may be a conflict here, between Hugh de Lacy, Earl of Ulster and his father, Hugh de Lacy, 1st Lord of Meath. According to the Encyclopaedia Britannica, it was the older Hugh de Lacy who came to Ireland in 1171 with Henry II, King of England. I've included information about both of them below. Either way, they'd still be direct ancestors. --JD ]
From the Encyclopaedia Britannica:
Ulster, Hugh de Lacy, earl of
b. c. 1176, d. , before Dec. 26, 1242, Ulster, Ire.
One of the most powerful Anglo-Norman lords in Ulster (in Ireland) in the first half of the 13th century.
He was the younger son of Hugh de Lacy, 1st lord of Meath. For a time he was coadjutor of John de Courci in Leinster and Munster, but after 1200 the rivalry between the two developed into war, and in 1203 de Lacy drove de Courci out of Down and in the following year took him prisoner. He was rewarded by King John with grants of land in Ulster and Connaught, which were confirmed by a charter on May 29, 1205, on which date (or earlier) Hugh was created earl. He returned to Ireland with quasi-viceregal authority. In 1207 war broke out between the Earl of Ulster and the justiciar. This brought King John in person to Ireland, where he expelled the earl's brother, Walter de Lacy, from Meath, and compelled the earl himself to flee to Scotland.
For several years Ulster took part in the wars in France, and he did not return to Ireland until 1221, when he allied himself with the O'Neills against the English. In 1226 his lands in Ulster were handed over to his brother Walter, but they were restored to him in the following year, after which date he appears to have loyally served the king, being more than once summoned to England to give advice about Irish affairs. On his death he left no surviving legitimate children, and the earldom of Ulster reverted to the crown.
From the Encyclopaedia Britannica:
Meath, Hugh de Lacy, 1st Lord of
d. July 25, 1186, Durrow, Leinster, Ire.
One of the Anglo-Norman justiciars of Ireland who went to Ireland with England's King Henry II in 1171.
Hugh de Lacy was granted (c. March 1172) the lordship of Meath for the service of 50 knights and was left as constable of Dublin and justiciar when Henry returned to England in April 1172. Hugh de Lacy returned to England later in the same year; in 1173 he fought for Henry in Normandy, defending Verneuil. He was appointed to succeed William Fitz Audlin as procurator-general of Ireland in 1177 but was removed from office in May 1181, perhaps because he had married a daughter of Roderic, king of Connaught, without seeking Henry's permission. Apparently restored during the winter of 1181-82, he was finally suspended from office in 1184. Henry's son John, who had been created lord of Ireland in 1177, visited Ireland in 1185 and subsequently complained that Hugh de Lacy had intrigued against him.
According to Giraldus Cambrensis, Hugh de Lacy was an able and resolute governor but physically unprepossessing, swarthy, short, and ill-proportioned. He built many castles in his territory; the construction of one, at Durrow, had involved the demolition of an ancient and venerated monastery. While inspecting the building on July 25, 1186, Hugh de Lacy was decapitated by an assassin. His son Walter de Lacy (d. 1241) became 2nd Lord of Meath; a younger son, Hugh de Lacy (d. c. 1242), became 1st Earl of Ulster (1205).
