Sources, Comments and Notes:
"WILLIAM Longespee, illegitimate son of HENRY II King of England & his mistress Ida --- (1176-Salisbury 7 Mar 1226, bur Salisbury Cathedral). Earl of Salisbury 1196 by right of his wife. ... m (1196) ELA Ctss of Salisbury, daughter & heiress of WILLIAM FitzPatrick Earl of Salisbury & his wife Eléonore de Vitré ([1191/92]-24 Aug 1261, bur Lacock Abbey). ... William & his wife had nine children:
2. IDA Longespee (after 1206-after 1260). ... m firstly RALPH [III] de Somery Baron of Dudley, son of RALPH [II] de Somery & his wife Margaret Crassus (-before 1220). m secondly () as his second wife, WILLIAM de Beauchamp Baron of Bedford, son of JOHN de Beauchamp & his wife --- (-1260).
9. IDA Longespee (-after 10 Apr 1262). The Book of Lacock names "Isabellam de Vescy…Elam…Idam de Camyle" as the daughters of "Guillelmus Longespe ex…Ela", adding that Ida married "Walterus filius Roberti" by whom she had "Catarinam et Loricam …velatæ …apud Lacock, Elam, quam duxit primo Guillelmus de Dodingseles, de qua genuit ---, Robertum, qui Dernogoill ---". This second daughter called Ida must have been a different person from his older sister also named Ida, as the latter received dower from her second husband William de Beauchamp after his death in 1260, so clearly could not have married Walter FitzRobert before 1247.
m (before 1247) WALTER FitzRobert of Woodham Walter, Essex, son of ROBERT FitzWalter of Woodham & his second wife Rohese --- (-shortly before 10 Apr 1258). Walter & his wife had four children:

2. CATHERINE. ...
3. LORICA. ...

"... Ida. She was married to Walter Fitz-Robert, son of the famous Robert Fitz-Walter, "the Marshal of the army of God," who headed the confederated Barons against King John. He succeeded his father in 1234, and died in 1257; leaving a son Robert, the ancestor, by Devorgoil, daughter of John de Burgh, of the long line of Barons Fitz-Walter, of Essex. Ida had also' three daughters: Katharine and Lorica, both nuns at Lacock; and Ela, married1 to William de Odingsells, of Maxstoke in Warwickshire; of whom this anecdote has been preserved by Matthew Paris, that at a tournament at Brackley in 1249, after the party of foreigners headed by the King's step-brother William de Valence, had obtained the victory, with the assistance of Richard Earl of Gloucester, who had previously supported the English party and was much blamed for changing sides, they used very ill William de Odingsells, a brave knight, who sided with the bachelors (militem strenuum, qui Bachelariis annumerabatur). Sir W'illiam de Odingsells left a son Edmund, who died soon after, and four daughters, who became coheirs: 1. Ida, married to John Lord Clinton, of Maxstoke in her right, and lineal ancestor of the present Duke of Newcastle; 2. Alice, wife first of Maurice de Caunton, and secondly of Ralph de Perham; 3. Ela, married first to Peter de Bermingham, and secondly to Eustace le Poer; and 4. Margaret, married to John Lord Grey of Rotherfield. Ela de Bermingham had a daughter Ela, the wife of Philip Purcel."
