So prosperous had this trade proved to be, that the higher ranks no longer considered it an indignity to engage in this and other pursuits. It required men of the resolution and prowess of Do’ull Mac Iain ‘ic Sheumais to run the gauntlet of the mauraders who were out to steal whole herds on the road between Skye and the markets of Crieff and Falkirk.

(History of Eriskay1580's - 1780's AD The first historical figure associated with Eriskay is Domhnull Mac Iain 'Ic Sheamais, the celebrated warrior bard and one of the most vivid characters in the long history of Clan Donald. From his island base he would answer any call to defend the interests of the clan with his mighty sword, the 'Cuig Mharg' which he named after the five merks he paid for it.
Donald was also a skilled poet and fragments of his work have passed into the oral traditions of Skye and the Uists. Donald died c 1650 in the home of his daughter at Gesto, on the Isle of Skye. His son James MacDonald followed in the tradition of his father and fought under Montrose in the campaigns of the 17th century, losing both his legs in the process.Despite his injuries, he returned to Eriskay and was succeeded by his son James who was tacksman of Eriskay in the latter part of the 17th century. This James had a son Donald and he had a son Angus. Angus died without issue some time after 1745 and so ended over 200 years of unbroken occupancy of the island by his family.
