Orderic Vitalis records that “Rogerius de Toenio” founded “cœnobium Castellionis alias de Conchis”. "…Rodgerii filii Rodulfi…Rogerii de Conchis" subscribed the charter dated to [1040] under which "Vuillelmus Ricardi magni ducis Normannorum filius" donated property to the abbey of Jumièges.
Roger’s place of burial is confirmed by the charter dated to [1130] under which Henry I King of England confirmed the foundation of Conches by "Rogerius senior…", quoting the confirmation by "Radulphus de Totteneio cum Godehilde matre mea" for the burial of "patris mei Rogerii". 1
