peninsula in north Donegal. It was around this period that the Victorians' enthusiasm for railways began to wane, and the Lough Swilly company was one of many that rarely made a profit. This was disastrous for Macneill as many of his commissions were to be rewarded through share dividends on any profits. He had also unwisely made himself financially liable for calls on shares for unprofitable railway companies.
With his income dwindling, Macneill became utterly impoverished. A fire in 1857 destroyed the principal industrial enterprise on his estate, the linen-mill and factory employing over 300 men, and this had been uninsured. He was then forced in 1868 to sell Mountpleasant House, his home in north Louth, which he had designed and built, and he moved to Surbiton and then London. He later became blind, abandoned by his friends and pupils, reportedly surviving on a pittance earned from making matchboxes in the single room where he lodged. He died at his son Torquil's house in
