He was a Justice ofthe Forest 1185-1189, sheriff at various times of of Northants, Essex,Herts, Staffordshire, Yorkshire, Westmoreland, Bedford, and Bucks.

Subject: MANDEVILLE/Earldom of Essex descent
The two most recent editions of the Weis books (MCS4 and ARCC7) showGeoffrey Fitz Piers, Earl of Essex as son of Maud de Mandeville, daughterof Geoffrey de Mandeville, Earl of Essex. I suspect that the derivationof this claim is a misreading of a table in CP, vol. 5 (Essex), where theparents of Fitz Piers, Piers and Maud (as well as Maud's other husband),are placed under the horizontal line connecting the children of Geoffreyde Mandeville, but without a verticle connection to that line. (In
other words, they were tucked in there for the sake of spacial layout,without intending to suggest a relationship.)
The accepted and documented descent of the Earldom of Essex to
Geoffrey Fitz Piers runs through his first wife, Beatrice de Say, who wasgranddaughter of Beatrice, sister of Geoffrey de Mandeville. That thisdescent was the determining factor in the grant of Essex to Geoffrey FitzPiers can be seen from the passing of Essex to de Bohun following thedeath of the sons of Geoffrey Fitz Piers and Beatrice de Say, bypassingGeoffrey's heir male, John Fitz Geoffrey, son by his second wife Avelinade Clare. Were there a "better" descent from Mandeville through themother of Geoffrey Fitz Piers, then John Fitz Geoffrey surely would havebeen the heir. Based on this, I do not think Maud, mother of GeoffreyFitz Piers could have been daughter of Geoffrey de Mandeville.
