Irish families fled the English-colonized Ireland in record numbers during the 19th century for North America. Many of those destitute families died from disease during, and even shortly after, the long journey.

Those in the urban centers would labor in the manufacturing sector, whereas those in work camps would to build critical infrastructures such as bridges, canals, roads, and railways. Regardless of when these Irish immigrants came to North America, they were critical for the rapid development of the young nations of the United States and Canada. Early immigration and passenger lists have recorded many early immigrants bearing the name of O'Hartigant: James, Michael, Patrick and Thomas Hartigan arrived in Canada in 1839; Michael Hartigan arrived in Baltimore with his wife and five children in 1820.
