University of Galway Professors Brendán Mac Suibhne and Daniel Carey talk to Ger about a digital repository of emigrant letters that is available to view online. Spanning a period of almost 400 years, the letters give detailed insights into the ways in which generations of Irish people struggled and succeeded in the new world. The material was gathered by American historian Kerby Miller, as part of research he conducted into the experiences of those who travelled to North America.
