Who We Are

Founded in 1836, the AOH prides itself on its founding principles of Friendship, Unity, and Christian Charity. We promote a solid loyalty to country, community, and God. We believe in aiding the Irish people's advancement, aspirations, and endeavors while fostering peace and unity in all of Ireland.

Here on Long Island, Suffolk County is proud to hold nine AOH divisions: Babylon, Bayshore, East Islip, Hampton Bays, Huntington, Patchogue, Port Jefferson, Selden, and Smithtown. Each division serves its local community while upholding our shared values and traditions.

If you are interested in joining the prestigious ranks of this noble organization, please visit our Divisions page and reach out to your local division for a membership application. To be eligible for membership, men must be Catholic and of Irish descent.
