Jeff Cleary of Albany's Irish American Heritage Museum () says the city's Celtic community dates back to the early 1800s, when laborers came from the old country to help build the Erie Canal. "Then the Great Famine struck and people came to Albany because they had relatives or connections here to get work through a cousin or a long-lost son," he says. Ultimately, so many Irish immigrants flocked to the south side of New York's capital city that the neighborhood is still called Limerick. Albany also hosts two Irish cultural organizations, the Capital District Celtic Cultural Association and the Capital District Irish American Center/Albany Ancient Order of Hibernians. Both offer concerts and other cultural activities, while Cleary says more than a half-dozen shops in an around Albany import authentic Irish butter, cheese, clothes and other goods.
