In 1329, the ailing Robert Bruce came to pray at Ninian's shrine. His journey to Whithorn may have been painful for he died three months later. It is now believed that the king was suffering from a wasting disease and not leprosy as previously thought.
According to records, Robert Bruce's son, David II, was miraculously cured at Whithorn. At the Battle of Neville's Cross in 1346, David II is said to have received an arrow wound that never fully healed, but after visiting Ninian's tomb the injury was cured.
