Notes:
                   Geoffrey de Mandeville, who like his fellow (the 2nd (meaning AlgernonCapell, 2nd Earl of Essex of the 1641 creation)) Earl of Essex of thepresent creation was Constable of the Tower of London, was created Earlof Essex in 1140 by King Stephen.  He already held numerous manors inBerks, Bucks, Essex, Herts, and Middlesex, which had belonged to hisgrandfather, another Geoffrey, at the time of the Domesday Survey in1086.  The family originated in Normandy, but precisely where is unclear,since there are several place names there akin to Mandeville (which seemsoriginally to have been in Latin 'Magna Villa' or "Great Town").  DeMandeville later sided with the Empress Maud, who granted him a moregenerously framed charter, including a clause making the post ofConstable of the Tower hereditary.  Later still de Mandeville again sidedwith Stephen but subsequently rebelled yet again.  His son was recreatedEarl of Essex by Maud in Jan 1155/6, the rebellious habits of the fatherand perhaps also the appointive nature of earldoms at the time requiringa regrant.

After the death of the 3rd de Mandeville Earl, right to the title passedthrough a female branch but these descendants of the original deMandevilles took the old family name (Mandeville) and were recognised asEarls of Essex in the time of King's John and Henry III.  [Burke'sPeerage, page 1004]

Cokayne's "Complete Peerage" (Essex, pp. 113-116), says that, for reasonsthat are somewhat obscure, KING STEPHEN, made him Earl of Essex, thenproceeds to detail Geoffrey's frequent switching of support for theEMPRESS MAUD and for KING STEPHEN in their contest for the throne.  AboutOct 1143, he was accused of treason, but he ridiculed the charge.  Hewas, however, arrested and imprisoned until he surrendered his castles toavoid being hanged.  He then broke into open revolt, seized and fortifiedthe Abbey of Ramsey, sacked Cambridge, and ravaged the fen country,until, when beseiging Burwell Castle, having removed his headpice onaccount of the heat, he was mortally wounded by an arrow.
