The name of an obscure Irish female saint is found in some of the Irish calendars at September 18. As Canon O’Hanlon explains below, the name of Gema of Riacc Innse is found in the Martyrology of Tallaght and in the Martyrology of Gorman. Her name is absent though from the Martyrology of Oengus and from the Martyrology of Donegal:
St. Gema, Virgin, of Riacc Innse.
