Sibella de Mandeville

In 1287 Henry Bodrugon married Sybil de Mandeville (29 September 1264-c.1307) daughter of an unknown Mandeville and his wife Alice Giffard. Sybil's grandparents were Hugh Giffard and Sibyl, daughter and co-heiress of Walter de Cormeilles. From 1239 until his death in 1246 Hugh was responsible for raising the young prince, later King, Edward I. Her maternal uncles were the Lord Chancellors of England, Walter Giffard, Archbishop of York, and Godfrey Giffard, Bishop of Worcester. Her aunt Mabel was the Abbess of Shaftesbury Abbey. Sybil was the widow of Peter le Poer (d. 4 April 1283), likely related to Eustace le Poer who, together with Thomas de Mandeville, brought an army from Ireland to Scotland to fight for Edward I of England. Sybil was lady of the Queen’s chamber to Eleanor of Castile and her children were still with the Queen's children in 1289-90. She was buried in Glasney College and her son Sir Otto paid for the Bodrugan Chantry to be built there in his parents' honour.

Henry and Sybil had two children:

Sir Otto de Bodrugan (b. 6 January 1290 - d. 6 September 1331), married Margaret de Champernown alias Campo Arnulphi (d. 1360).

Johanna (b. 1285), married Sir Henry de Champernoune Campo Arnulphi.

These children and their spouses feature heavily in the novel The House on the Strand by Daphne du Maurier.
