The name Tourny reached English shores for the first time with the ancestors of the Tourny family as they migrated following the Norman Conquest of 1066. The Tourny family lived in Shropshire. Their name, however, is a reference to Tournay-Sur-Dive, Normandy, the family's place of residence prior to the Norman Conquest of England in 1066.
The surname Tourny was first found in Shropshire where they were Lords of the manor of Kinnersley and other lands in that shire, which the Domesday Book in 1086 shows as being an under tenant of Earl Roger. They were originally castellans of the castle at Exmes for the Counts of Exmes, the Montgomerys. The Tournay estates were originally at Tournay-Sur-Dive at Orne in the arrondisement of Argentan in Normandy.

"Upon the redistribution of the conquered province of Mercia, when Earl Roger de Montgomery entered Shropshire to possess and rule, Gerard de Tornai, one of his followers, received as the meed of service, eighteen valuable Saxon manors, of which the largest was Sutton.

At any rate, De Tornai's career in Shropshire terminated, about 1088, in a total and absolute forfeiture. The disinherited Baron had a daughter, Sibil, wife of Hamo Peverel, who by special favour acquired a succession to the forfeited estate, under a title from the first ambiguous."- History and Antiquities of Shropshire.

Simon of Tournay (fl. 1184-1200), was an early English schoolman, said to have been a native of Cornwall. His name was spelt many ways including Thurnai, Thurvay and in Latin as Thurnaius. "Whether he received that name because he was a native of Tournay, or because he subsequently held a canonry in the cathedral there, is uncertain. " 3
