In baronial party against King John
----------------------
ROBERT MARMION, son and heir. He witnessed several charters of Henry II between 1174 and 1181. In October 1181 he completed his father's gift to Barbery Abbey. He took an active part in judicial affairs, occurring first as a justice of assize at Caen in 1177. He acted as a justice in the King's court or as itinerant in several counties in England between the years 1184/5 and 1205, and was of the Barons' party against King John. He was Sheriff of co. Worcester between 1185 and 1189. At Michaelmas 1194 he was acquitted of scutage in co. Lincoln by reason of his military service in Normandy.
He married, 1stly, Maud DE BEAUCHAMP (j). He married, 2ndly, Philippe. He was dead by 15 May 1218. In 1221 Philippe, as widow of Robert Marmion and mother of Robert the younger, claimed dower in Tamworth, Middleton, and Scrivelsby against her stepson Robert the elder, son of Robert by Maud de Beauchamp.

(j) Tamworth had been granted to William son of Walter de Beauchamp by the Empress Maud circa 1141. Round suggests that "in their rivalry for Tamworth, the Marmions embraced the cause of Stephen, and the Beauchamps that of Maud, their variance being terminated under Henry II by a matrimonial alliance." This alliance presumably took place before King Henry II's charter of 1155 to Robert Marmion the second, when his son Robert, afterwards the justice, could not have been more than a boy
