About the Society

Muintir Mathuna - The O Mahony Society, is the international association of members and friends of the O Mahony Clan. The O Mahonys (O Mathuna in Gaelic) descend from Mathuin (Mahon), son of Cian mac Maol Muadh, Prince of Raithleann, and Saidhb, daughter of Brian Boru. Mathuin became Prince of Raithleann and chief of the Ui Eachach Mumhan in 1014 A.D.

The O Mahony Society's purposes are to foster studies on the history of the Clan, to promote interest in Irish culture and heritage, to promote and encourage the restoration and preservation of the historical sites associated with the Clan, and to promote fellowship among members.

The Society's activities embrace historical and cultural events via social meetings, a periodic newsletter, and the O Mahony Journal. The programme includes an annual Gathering of the Clan each summer in Ireland, and a Get-Together in the United States, Australia, New Zealand, or other countries as possible. Society members residing in countries outside of Ireland develop additional programmes in areas of interest and/or where members are concentrated.
