The earliest mass migration of the Irish to America

In Scotch Irish Pioneers in Ulster and America, his classic study of the eighteenth-century “Scots-Irish” exodus from Ulster to America, Charles Knowles Bolton cites court records, newspapers, correspondence and other primary sources. The book provides specific details about immigrant communities in New England, Pennsylvania, and South Carolina, and lists many immigrants and their origins in Ulster.

In a time before microfilms, scanned newspapers, and Internet searches, Bolton culled through early American newspapers to locate the arrival of ships from Ireland bearing passengers for New England.  He combed state and local archives, viewed correspondence, and reviewed town records to assemble his data.

Bolton studied and reproduced data from the session book of Aghadowey in Ireland, locating the Irish residences of immigrants and included drawings of the houses. (A copy of the session book in the NEHGS collection may be searched here.) He provided sources for many of his assertions in footnotes, so that readers can look for the original source material. The appendices include a list of ships arriving in Boston area ports from 1714 to  1720, members of the Charitable Irish Society in Boston, and the names of fathers in Presbyterian parish registers from 1730 to 1736.

Illustrated with portraits, maps and views of buildings and landscapes, this enduring study of the earliest mass migration of the Irish to America remains an important source for twenty-first-century researchers.
