O’Dea Clan members from throughout the world gathered at Dysert O’Dea in 1990 for the first time since the Flight of the Wild Geese in 1691. Meeting in nearby Ennis, these Clan representatives formed the Dysert O’Dea Clan Association (as Gaélige: Cumann Chlann Díseart Ó Déaghaidh) to facilitate and encourage exchange between Clan members and to promote research into the history and genealogy of the O’Dea Clan.
