Maille's
floruit is uncertain. His descendants began using his name as a
surname in the late 11th/early 12th century. The earliest members of the family to use O'Maille/O'Malley as a surname would have been his great-grandson, Dubhdara. Knox gives a
pedigree of
Domnall Ruadh O Maille, king of Ui Maill, who was killed in 1337. It traces his descent from Maile thus:
Domnall Ruadh mac Brian m. Domnall m. Muiredhach m. Domnall Finn m. Muiredhach m. Dubhdara m. Muiredhach m. Dubhdara m. Flannabhra m. Seachnusach m. Maille. The surname O Maille/O'Malley/Malley is one of the most common surnames in County Mayo, and features strongly in the area's history. ==References==
