Long ago, Calum Sgaire (Macolm MacAulay) was a sailor from Bosta on the Isle of Lewis. "Sgair" means "splice," so his nickname suited his profession as a mariner. He and one Margaret MacLeod had arranged a tryst on a certain hill, and planned to elope, because her family wanted her to marry an old man of some means. The tryst didn't work out - they failed to meet - and Calum sailed off the next day. Young Margaret had to marry the old man, but she lived less than a year after that.
