Context is often as important as the details we discover when researching family history. Here's a book that might be a good reference and companion to other volumes on your Irish genealogy bookshelf:

A History of Ireland in 250 Episodes by Jonathan Bardon 

Jonathan Bardon covers all the obvious things: the invasions, battles, development of towns and cities, the Reformation, the Georgian era, the Famine, rebellions and resistance, the difference of Ulster, partition, the twentieth century. What makes his book so valuable, however, are the quirky subjects he chooses to illustrate how history really works: the great winter freeze of 1740 and the famine that followed; crime and dueling; an emigrant voyage; evictions. These episodes get behind the historical headlines to give a glimpse of past realities that might otherwise be lost to view. The author has retained the original episodic structure of the radio programs. The result is a marvelous mosaic of the Irish past, delivered with clarity and narrative skill.
