Migration of the Monyhan family

A great mass of Ireland's native population left the island in the 19th century, seeking relief from various forms of social, religious, and economic discrimination. This Irish exodus was primarily to North America. If the migrants survived the long ocean journey, many unfortunately would find more discrimination in the colonies of British North America and the fledgling United States of America. These newly arrived Irish were, however, wanted as a cheap source of labor for the many large agricultural and industrial projects that were essential to the development of what would become two of the wealthiest nations in the western world. Early immigration and passenger lists indicate many people bearing the Monyhan name: Daniel Moynihan, who was naturalized in Detroit in 1834; Timothy Minihan and his family, who immigrated to St. John, New Brunswick in 1834; James and John Moynagh, who were recorded in Nova Scotia in 1843.
