between 1845 and 1851 over 15000,000 people emigrated from Ireland which was more than had left in the previous half century
The main reason for the surge in Irish immigration to the U.S. in the mid-nineteenth century was the Great Famine in Ireland, which led to widespread poverty, famine, and lack of opportunities. Many Irish immigrants sought better economic prospects and a chance for a new life in America.
The largest influx of the Irish started in 1845/6 and ran for 15-20 years. It was caused by Irish families trying to escape the Potato Famine which was ravaging Ireland at that time. Earlier, in the period 1817-25, large numbers of Irish laborers came over to work on the construction of the Erie Canal in New York State. Those were the two big 'jumps' in the Irish immigration.
Irish <Fenian> immigration began and escalated thereafter.

There was a huge immigration of Irish citizens to the USA during the potato famine.
The Irish Jews were such a small population (<1,000 people) that there really was no wave of Irish Jewish immigration to America. Additionally, since most Irish Jews lived in the cities, they were not subject (as strongly) to the Irish Potato Famine, which was responsible for the largest percentage of Irish immigration to the US.
