Melrose Abbey, the abbey of Dryburgh commenced on a rebuilding programme on a grander scale, but building in stone against a background of an insecure income soon ensured that the construction work would not be completed quickly. Also at this time, the monastery became embroiled in a series of legal proceedings regarding land ownership and tithe revenues resulting, in April 1221, in the Pope's legate having to spend some time at Dryburgh to adjudicate. The construction effort was protracted and endured into the 1240s and with debts continuing to mount to the point that David de Bernham, Bishop of St Andrews gave Abbott John permission on 21 April 1242 to appoint his canons as vicars to the supporting churches stating … since they have been burdened by grinding debts both on account of construction of the monastery and also on account of other and various necessities. Pope Innocent IV granted to the abbey in 1246, on the anniversary of its consecration, an indulgence lasting forty days intended to attract visitors who would hopefully be generous with their alms-giving. Additionally, he also provided a suspension of the requirements to create pensions and benefices that might deplete the abbey's revenues, and importantly, safeguarded the monastery, its property and the canons themselves against legal redress. Abbott John was blamed for ineffectual financial management and was required to resign and, on 13 January 1255 Pope Alexander IV wrote to the Bishop of St Andrews (position vacant at the time) and to Nicholas de Prenderlathe, abbot of Jedburgh demanding that most of the abbey's income be diverted to paying off debts while only a basic level of income was to be retained for day to day expenses. Slow improvement in the abbey's finances took place over the next forty or so years in a period of relative stability. However this improvement was only relative; Dryburgh's neighbouring monasteries with their much more extensive grazing lands provided the main source of a much greater income. Changing patronage Hugh de Morville's line had died out in 1196 on the death of his grandson, William, and the estates passed to William's sister, Helen, whose husband was Lochlann, Lord of Galloway. The semi-independent Lords of Galloway were much wealthier than the de Morvilles but even they could not lavish large amounts on all their dependencies. Lochlann was already benefactor to four religious houses in Galloway that included his own Cistercian
