Transatlantic Crossings · 8 Embarkation Ports

Historic Irish Departure Ports

Between 1845 and 1950, more than six million Irish men, women, and children bade farewell to their homeland from these eight coastal harbors. From the timber barques of the Famine era to the great White Star and Cunard liners, each port had distinct regional feeder routes connecting specific Irish counties with American entry points.

Understanding Transatlantic Passenger Manifests

Prior to the 1890s, port passenger manifests recorded at Castle Garden or Boston often merely stated "Ireland" as the passenger's nationality. Tracing the departure port is one of the most effective methods to narrow down an ancestor's home county: emigrants rarely traveled overland beyond their nearest regional port or railway feeder line.
