The Ancient Order of Hibernians is America’s oldest Irish Catholic Fraternal Organization founded concurrently in the coal-mining region of Pennsylvania and New York City in May,1836. The Order can trace its roots back to a series of similar societies that existed in Ireland for more than 300 years. Today the AOH exists in America, Canada, Ireland, England, Wales and Scotland, however, while the organizations share a common thread, the American AOH is a separate and much larger organization.
