The death of Geoffrey was a fatal blow to the power of the fenland rebels. According, indeed, to one authority, his brother-in-law, William de Say, met his death on the same occasion,[700] but it was the decease of the great earl which filled the king's supporters with exultant joy and hope.[701] For a time Ernulf, his son and heir, clung to the abbey fortress, but at length, sorely against his will, he gave up possession to the monks.[702] Before the year was out, he was himself made prisoner and straightway banished from the realm.[703] Nor was the vengeance of Heaven even yet complete. The chief officer of the wicked earl was thrown from his horse and killed,[704] and the captain of his foot, who had made himself conspicuous in the violating and burning of churches, met, as he fled beyond the sea, with the fate of Jonah, and worse.[705] Chroniclers and genealogists have found it easiest to ignore the subsequent fate of Ernulf (or Ernald) de Mandeville.[706] He has even been conveniently disposed of by the statement that he died childless.[707] It may therefore fairly be described as a genealogical surprise to establish the fact, beyond a shadow of doubt, not only that he left issue, but that his descendants flourished for generations, heirs in the direct male line of this once mighty house. Ernulf himself first reappears, early in the following reign, as a witness to a royal charter confirming Ernald _de Bosco's_ foundation at Betlesdene.[708] He also occurs as a principal witness in a family charter, about the same time.[709] This document,[710] which is addressed by Earl Geoffrey "baronibus suis," is a confirmation of a grant of lands in Sawbridgeworth, by his tenant Warine fitz Gerold "Camerarius Regis" and his brother Henry, to Robert Blund of London, who is to hold them "de predictis baronibus meis." The witnesses are: "Roesia Com[itissa] matre mea, Eust[achia] Com[itissa], Ernulfo de Mannavilla fratre meo, Willelmo filio Otuwel patruo meo, Mauricio vicecomite, Willelmo de Moch' capellano meo, Otuwel de bouile, Ricardo filio Osberti, Radulfo de Bernires, Willelmo et Ranulfo fil' Ernaldi, Gaufrido de Gerp[en]villa, Hugone de Augo, Waltero de Mannavilla, Willelmo filio Alfredi, Gaufredo filio Walteri, Willelmo de Plaisiz, Gaufrido pincerna." He is, doubtless, also the "Ernald de Mandevill" who holds a knight's fee, in Yorkshire, of Ranulf fitz Walter in 1166.[711] But in the earliest Pipe-Rolls of Henry II. he is already found as a grantee of _terræ datæ_ in Wilts., to the amount of £11 10_s._ 0_d._ (blanch) "in Wurda." This grant was not among those repudiated by Henry II., and Geoffrey de Mandeville, Ernulf's heir, was still in receipt of the same sum in 1189[712] and 1201-2.[713] Later on, in a list of knights' fees in Wilts., which must belong, from the mention of Earl William de Longespée, to 1196-1226, and is probably _circ._ 1212, we read: "Galfridus de Mandevill tenet in Wurth duas partes unius militis de
