In his new home James Dawson soon prospered as a merchant and ship-owner, and later as a publisher, and in a few years he was head of one of the most successful business firms in Eastern Nova Scotia. In 1818 he married Mary Rankine, a Scotch girl from Lonerig, in the parish of Salamannan, who had emigrated to Nova Scotia after her parents' death with her brother William, the only other member of her family. Like the other pioneers of that time, they, too, were resolved to make a new home and to restore their shattered fortunes in the new world. To James Dawson and Mary Rankine two children were born, William and James, the latter of whom died while still a boy. William Dawson was born in the town of Pictou, Pictou County, Nova Scotia, on October 13th, 1820, and there he received his early schooling. His parents believed in the value of education. Early in his career they determined that he should have whatever school privileges the country provided, and that he should later receive a college training. Many years afterwards he wrote: "To this day I cannot recall without deep emotion the remembrance of the sacrifices they made, and of the anxieties they incurred to secure for me opportunities of improvement.... I would specially record with gratitude that, at a time when he was in straitened circumstances, my father contributed liberally in aid of educational institutions then being established in Pictou, with the view of securing their benefits for his sons, and that he and my mother aided and stimulated our early tastes for literature and science."
