Along with the Irish diaspora to North America and the opportunities it offered, the Lynch Family probably immigrated sometime in the late 17th to early 18th centuries, if not before. Out of the 56 delegate signatures of the United States Declaration of Independence, eight were of Irish descent and one of them is of Thomas Lynch Jr, firmly establishing the Lynch surname as Irish-American for the first time.
During America’s early history many people immigrated to the United State from Ireland, but many modern day American Lynches are decedents of Jonack Lynch. Jonack Lynch emigrated from Ireland to South Carolina in 1670 and his grandson, Thomas Lynch was a member of both Continental Congresses. Jonack Lynch’s great-grandson, also called Thomas Lynch, was the Thomas Lynch that signed the United States Declaration of Independence.
Irish Americans, defined as citizens of the United States who can trace their ancestry back to Ireland in some way, now account for an estimated total of 32 million people, or nearly 12% of the total US population.
Immigration records compiled from official New York Passenger Lists indicate that approximately 70 percent of immigrants with the surname Lynch originated from Ireland. The other 30 percent came from England, Scotland and a very small percentage came from Germany. Passenger lists also show that the majority of Lynches immigrated between 1850 and 1891 with a severe spike in 1851. This spike corresponds with the Irish Potato Famine, a period of mass starvation and disease in Ireland. The Great Famine, as it was called by the Irish, resulted in the death of approximately one million people and the emigration of another million.
The immigration status of many Lynches determined their residence and occupations. According to 1920 Census Records, 20 percent of Lynches listed their occupation as farmers compared to 35 percent of the general public. In contrast, 16 percent of Lynches were listed as laborers, compared to nine percent of the general public. These statistics and the location of most Lynches in the 1920es (New York, New Jersey and Illinois) suggest that they were employed at large factories, often with low pay and deplorable working conditions.
