Early in the nineteenth century, there were some famines in Ireland, culminating in the Great Famine of 1845 - '49, when about a million people died, and a further million went into exile.

Consequences were devastating and caused a dramatic change in the Irish social and economic fabric.

County Mayo, located on the West coast of Ireland in the province of Connacht, had a population at the time of the Great Famine of 388,887 people which declined by 29 percent to 247,830 people due to deaths and emigration.

Emigration became a long-term legacy of the Famine.

Often emigrants came from the workhouses. Emigration Commissioners offered free passage, clothing and a little money to people who wanted to emigrate.

Unfortunately, sometimes, the reality was different; many escaped at night time from the workhouses climbing through windows and over high walls abandoning their children.

Emigrating families left behind hundreds of children.

Most emigrants from the county went to the USA, Canada, England, Scotland and Australia, to become part of the significant Irish Diaspora scattered throughout the world.

By the end of the 19th century, the US cities of New York, Jersey City, Boston, Philadelphia and Chicago and UK cities of Liverpool, London and Manchester received the bulk of Mayo emigrants.

Emigration was the escape from the hunger. The most of emigrants could afford only cheapest passages on ships which left Mayo’s shores horrendously overcrowded. "Coffin Ship" was the term used to describe those ships.

They often had to provide their own food; water was shortly supplied. They were allowed to sleep on an allocation of very few square metres of timber. The poor sanitation and conditions aboard ensured diseases to spread. Many died at sea and did not reach their destination.
