In later generations, the lairds themselves became Presbyterian, preventing the island from becoming involved in the Jacobite risings, but it did ultimately bring a minor dispute to the island. In 1726, Presbyterianism was established in Rùm, quickly taking hold of the island's population (there were only around 150 people living on Rùm at the time). Nevertheless, Rùm had no permanent Protestant minister, and when one visited, he was obliged to conduct sermons in the open air, there being no church building.
