First found in Lancashire, where they had been granted lands by William the Conqueror for their assistance at the Battle of Hastings in 1066 A.D.

The Irish emigration during the late 18th and 19th century contributed to the melting pot of nationalities in North America, and the building of a whole new era of industry and commerce in what was seen as a rich, new land. Ireland'sGreat Potato Famine resulted in the worst economic and social conditions in the island's history. And in response to the hunger, disease, and poverty, during this decade the total number of emigrants to leave for North America rivaled all the previous years combined. Those from this decade that arrived on North American shores were not warmly welcomed by the established population, but they were vital to the rapid development of the industry, agriculture, and infrastructure of the infant nations of the United States and what would become Canada. Research into early immigration and passenger lists has shown many people bearing the name D'Alton: Philemon Dalton was a linen weaver who arrived on the ship "Increase" in the year 1635; four years after the "Mayflower." William Dalton is recorded as arriving on the "Goodfellow" in 1654.
