Douglas, William the Conqueror (Berkeley, Los Angeles: University of California Press, 1964), p. 94 Like Duke Robert, Roger began taking properties that belonged to the church. These included  half the town of Bernay.Kathleen Thompson, 'The Norman Aristocracy before 1066; The Example of the Montgomerys', Historical research; the Bulletin of the Institute of Historical Research, Vol. 60, Issue 123 (October 1987), p. 255 He took over a woodland at 'Crispus Fagidus' which belonged to Jumièges Abbey. He put an end to a market held by the same abbey and took it into his own domain.Cassandra Potts, Monastic revival and regional identity in early Normandy (Woodbridge, UK: The Boydell Press, 1997), p. 121 Later he seemed to have a change of heart. He returned the market to the abbey and paid restitution for their losses. After 1035 Roger seems to have lost favor with the young duke William. He signed an early charter of Duke William simply as 'Roger of Montgomery'.Kathleen Thompson, 'The Norman Aristocracy before 1066; The Example of the Montgomerys', Historical research; the Bulletin of the Institute of Historical Research, Vol. 60, Issue 123 (October 1987), p. 257 He apparently was no longer the viscount.
