Nolan, Janet. The St. Patrick's Day Shillelagh. Illustrated by Ben F. Stahl. Morton Grove, Ill.: Albert Whitman & Company, 2004.
The Irish potato famine forces Fergus' family to immigrate to the United States. Before leaving the old country, Fergus carves a shillelagh which becomes the family's reminder of their family's history through several generations. This is a great book to remind families that their story needs to be heard.
I don't know if this qualifies or not, but I'm submitting it to the Back to School Edition of the Carnival of Irish Heritage and Culture hosted by Small-Leaved Shamrock (details here). Since I have no known Irish ancestry, I don't spend a lot of time in primary sources that deal with the Irish. This children's book, however, was delightful.
