The Kerby Miller Archive at the University of Galway comprises copies of thousands of emigrant letters sent between the US (and some other countries) and Ireland between the late 1600s and 1950s, donated by Prof. Kerby A. Miller. He became interested in the experience of Irish emigrants to America, while studying at the University of California, Berkeley, during the early 1970s. In the many years that followed, he travelled the country seeking letters that had been sent to and from all parts of Ireland and its diaspora.
