First found in county Waterford where they were granted lands by Strongbow, Earl of Pembroke, for their assistance on his invasion of Ireland.

Irish immigration to North American began in the late 18th century as many Irish families desired to own their own land. This pattern of immigration grew slowly yet steadily until the 1840s. At that time, a failed crop and a growing population in Ireland resulted in the Great Potato Famine. Poverty, disease, and starvation ravaged the land. To ease their pain and suffering the Irish often looked upon North America as a solution: hundreds of thousands undertook the voyage. Their arrival meant the growth of industry and commerce for British North America and the United States. For the individual Irishman, it meant survival and hope, and the opportunity for work, freedom, and ownership of land. The early immigration and passenger lists revealed many bearing the name Barron: Ellis Barron who settled in Watertown in 1640 from Waterford; Robert Barron settled in Virginia in 1634; Elizeus Barron who settled in Woodbridge New Jersey in 1705.
