The church, or at least the nave, was originally built as a chapel by Roger, the second abbot of Byland (1142-1196). This was most likely to have been following the move to Old Byland in 1143. The monks had been given land near Tylas by members of the de Mowbray family, and the chapel appears to have been constructed for Hugh Malebiche, who was the de Mowbray’s steward, to obviate the need for him and his family members to walk all the way over to Old Byland for services. After Hugh’s death, Scawton passed to his grandson, Richard, who held some form of judicial role in York. In 1190, he was implicated in the massacre of the Jews, to whom he apparently owed large sums of money. His lands were subsequently confiscated, though he was allowed to buy them back after John assumed the throne.
