Following the death of King David, the patronage and privileges of the abbey were accorded to his grandsons Malcolm IV of Scotland and William I of Scotland, also known as William the Lion. The King's son, Henry, had preceded his father in death. The nave and the choir were built in the 13th century and were in place by the time Alexander III of Scotland married Yolande, daughter of the Comte de Dreux on 14 October 1285 at the church. The great abbey was said to contain the finery of the best of Norman and early English Architecture. The Abbey Church of St. Mary of Jedeworth was growing in stature and importance and the abbot was even invited to attend Scottish Parliaments. As well as the lands and chapels in southern Scotland, Jedburgh Abbey owned great lands in Northumberland. In 1296, the Abbot of Jedburgh swore fealty to Edward I of England at Berwick-on-Tweed.
