More than 7 million emigrants left Ireland since the 1600s in search of a better life. From the 1820s through the Great Famine and into the 1880s, one-third to one-half of all the immigrants to America sailed from Ireland. Today, according to the 1990 Census, 40 million Americans identify themselves ethnically as Irish, behind only British (50 million) and German (49 million).

Tracing those Irish roots has become a passion for many in recent years. It can be a challenge for genealogy novices, and even experienced searchers are always reminded that those who lived in desperate poverty in Ireland couldn't take pains to record family histories. But even the slimmest leads can turn into real treasures, if you're persistent—and lucky.
