Since my original post last week regarding the maternity of Juliane Fitz Maurice, various people have contacted me and requested additional information on the ancestry of her mother, Maud de Prendergast. In the intervening time, I've researched the matter and have developed a preliminary ahnentafel for Juliane Fitz Maurice and her mother, Maud de Prendergast, a shortened version of which is presented below. The ancestry of Maud de Prendergast includes some of the top medieval families of England, Ireland and France, including Quincy, Clare, Burgh, Lacy, Beaumont, Braose, St. Valery and Vermandois. If anyone has any corrections or additions to the information below, please let me know. The list of colonial immigrants who descend from Juliane Fitz Maurice is repeated following the ahnentafel.
Best always, Douglas Richardson

• Background Information. 924
Richard de Burgo, was granted, 17 Sep 1215, by King John, for his homage and service, all the land of Conaught, which his father held of the Crown. On 10 Mar 1227, he was sonstituted Lord Lieutenant of Ireland; in 1232, he built the castle of Galway, as he did that of Loughreagh in 1236. He was a person of such high authority and power, that in 1242, he went to Bourdeaux to meet the King of England, but died in that voyage in France, about the beginning of Jan 1243. He left issue by Hodierna de Gernon, daughter of Robert Gernon, (by Una, daughter of Odo O'Conor, son of Cahil Crovderg, or the red band, King of Conaught) Walter, his successor; William; Margery or Marcella, married to Theobald Butler, the third of that name; and Agnes, married to Henry Netterville, ancestor of the Lord Netterville.

~The Peerage of Ireland, Vol. I, p. 118-119

• Background Information. 479
Richard de Burgh, Lord of Connaugh (died 1243), Irish settler, is said to have been the son of William Fitzald Helm [q.v.], one of the early invaders of Ireland [Dugdale, Baronage, 'Burgh;' Lodge, Peerage of Ireland, 'Clanricafrde;' Benedictus, i. 25]; he is, however, described in the Close Rolls [Calendar, p. 551] as the son of William de Burgh, who received a large grant in Connaught from John, and was afterwards disseised by him. Richard appears to have made a pilgrimage to the shrine of St. James at Compstella in 1222 [Close Rolls]. The order of St. James had been founded about fifty years before; the saint was held in high estimation by the chivalry of England, and pilgrimages to his shrine were popular, for they had the character of military adventures, as well as of acts of devotion. On Richard's return he received grants of all the lands in Connaught, of which he and his father had been disseised by John, and thus became lord of a great part of the province.

In 1223 the king sent Richard de Burgh a Bristol ship laden with supplies, to help him in his war there [Close Rolls 1223-5; Excerpt. Rot. Fin. p. 128]. In the war with Aedh of Connaught in 1230, he led one of the divisions of the army under the command of Geoffrey de Marisco, and took part in a battle in which the Irish were defeated and Aedh was taken prisoner. When Peter des Roches succeeded in driving Richard, the Earl Marshall, into rebellion by his unjust treatment of him, he determined to draw him into Ireland that he might destroy him there. Accordingly he and his party wrote to the lords in Ireland, and excited them against him. This letter, which was sealed by the king, came, among others, to Richard, who joined the conspiracy made against the earl, and invaded his lands. The earl went over to Ireland to defend his lands, and Richard went with Geoffrey de Marisco and the rest to meet him. They offered to be his allies, and incited him to make war against the king's possessions that they might destroy him and divide his inheritance. None sought his life more eagerly than Richard. When the conspirators openly turned against him and prepared to give him battle (1 April 1234), Richard armed one of his Irish followers, a man of great strength, with his own armour, and charged him to slay the earl. The Irishman failed in his attempt, but the earl was mortally wounded somewhat later in the battle.

During the expedition of Henry III to Poitou, Richard and other Irish lords were persuaded by Maurice Fitzgerald to fit out a fleet and sail to join the king. They were met by the ships that guarded the coast of France. A storm separated the fleets, but the barons evidently had the worst of the engagement. Frightened alike by the rough weather and the attack of the French, they landed on a part of the coast that was unknown to them. Many perished of the hardships they had to undergo. Among them Richard died in the early part of 1243.

Richard de Burgh married Egida, daughter of Walter de Laci, and left an heir, Walter [q.v.], and other children. He is the ancestor of the house of Clanricard.
