 This sub-manor of Pishiobury originated in a grant of 74 "libartes" of land within the Manor of Sawbridgeworth in Braughing Hundred, which Geoffrey de Mandeville, 1st Earl of Essex, who died in 1144, made to Warin FitzGerold and Henry FitzGerold to hold by service of one Knight for each 20 libartes.Henry survived his brother, but his niece Margaret FitzGerold/FitzWarin inherited Pishiobury.She had married in 1200 Baldwin de Redvers, son of William de Redvers, 5th Earl of Devon, and in 1228 she levied a fine with William de Saye by which it was agreed that William and his heirs were to have free warren, a hunting right, throughout Sawbridgeworth.
