From Wikipedia - Geoffrey Fitz Peter, 1st Earl of Essex :

Geoffrey Fitz Peter, Earl of Essex, (Piers de Lutegareshale), (c. 1162 - 1213), was a prominent member of the government of England during the reigns of Richard I and John . The patronymic is sometimes rendered Fitz Piers

He was from a modest landowning family that had a tradition of service in mid-ranking posts under Henry II . Geoffrey's elder brother Simon was at various times sheriff of Northamptonshire, Buckinghamshire, and Bedfordshire. Geoffrey, too, got his start in this way, as sheriff of Northamptonshire for the last five years of Henry II's reign.

Around this time Geoffrey married Beatrice de Say, daughter and eventual co-heiress of William de Say II. This William was the son of William de Say I and Beatrice, sister of Geoffrey de Mandeville, 1st Earl of Essex . This connection with the Mandeville family was later to prove unexpectedly important. In 1184 Geoffrey's father-in-law died, and he received a share of the de Say inheritance by right of his wife, co-heiress to her father. He also eventually gained the title of earl of Essex by right of his wife, becoming the 4th earl.

When Richard I left on crusade, he appointed Geoffrey one of the five judges of the king's court, and thus a principal advisor to Hugh de Puiset , Bishop of Durham , who, as Chief Justiciar , was one of the regents during the king's absence. Late in 1189, Geoffrey's wife's cousin William de Mandeville, 3rd Earl of Essex died, leaving no direct heirs. His wife's inheritance was disputed between Geoffrey and his in-laws, but Geoffrey used his political influence to eventually obtain the Mandeville lands (but not the earldom, which was left open) for himself.

On 11 July 1198 , King Richard appointed Geoffrey Chief Justiciar , which at that time effectively made him the king's principal minister. He continued in this capacity after the accession of king John until his death on October 14, 1213.[1] On his coronation day the new king also recognized Geoffrey as Earl of Essex .
