  Research Notes:

From Wikipedia - Roger Bigod, 2nd Earl of Norfolk :

Ida de Tosny was a royal ward and mistress of King Henry II, by whom she was mother of a young son William Longespée, 3rd Earl of Salisbury ) (b c. 1176 -March 7 , 1226 ). Ida was not the first English royal ward to be taken as mistress by a King who was her guardian; that honour probably belongs to Isabel de Beaumont (Elizabeth de Beaumont), daughter of Robert de Beaumont, who fought at the Battle of Hastings with the Conqueror. That king's youngest son made Beaumont's daughter his mistress. Ida's ancestry was unknown for many years, but a charter by her eldest (illegitimate) son refers to his mother as the "Countess Ida" which pins her down to the wife of Roger Bigod. For Ida's ancestry, see "Some corrections and additions to the Complete Peerage: Volume 9: Summary" and Marc Morris's The Bigod Earls of Norfolk in the Thirteenth Century

Ida married Roger Bigod Baron le Bigod, 2nd Earl of Norfolk, son of Hugh Bigod 1st Earl of Norfolk and Juliana de Vere, in Dec 1181. (Roger Bigod Baron le Bigod, 2nd Earl of Norfolk was born about 1144 in <Norfolk, Norfolk>, England, christened in Framlingham, Suffolk, England, died before 2 Aug 1221 in Thetford, Norfolk, England and was buried in Thetford, Norfolk, England.)

Ida next had a relationship with Henry II "Curtmantel" King of England, son of Geoffrey V Plantagenet Count of Anjou, Duke of Normandy and Empress Matilda Countess of Anjou. (Henry II "Curtmantel" King of England was born on 5 Mar 1132 in Le Mans, (Sarthe), Maine, (France), died on 6 Jul 1189 and was buried in Fontévrault Abbey, (Fontevraud-l'Abbaye), (Maine-et-Loire), Anjou, France.)
