Maille mac Conall, member of the Umhaill, ancestor and eponym of the O'Malley family of County Mayo.
His father's brother, Colman, is given as ancestor of an O'Colman family, while Fergus, a son of Flannabhra mac Cumusgrach (died 773), is given as an ancestor of the family of Fergus and the Muinter Rooney.
He appears in a number of genealogical collections, such as Dubhaltach MacFhirbhisigh's Leabhar na nGenealach.
Hubert T. Knox made use of this source when drawing up family trees of the Ui Mail, and gives the O'Malley genealogy in his book, The History of Mayo.
The earliest members of the family to use O'Maille/O'Malley as a surname would have been his great-grandson, Dubhdara.
