He was a son of Domhnall Mór Ó Domhnaill, King of Tír Chonaill (died 1241), a man who was married to Lasairfhíona, daughter of Cathal Crobhdhearg Ó Conchobhair, King of Connacht. Maol Seachlainn had two brothers: Gofraidh (died 1257) and Domhnall Óg (died 1281).
Reign
In 1245, Maol Seachlainn ravaged North Connacht. The following year, Maurice fitz Gerald invaded Tír Chonaill, seizing several hostages and secured them within Sligo Castle. The year afterwards, Maol Seachlainn counter-attacked Maurice, and the hostages were killed in retaliation.
In 1247, Fitz Gerald invaded Tír Chonaill again, and was halted at Ballyshannon by the combined forces of Cineál Chonaill and Cineál Eoghain. When Cormac Ó Conchobhair forded the River Erne and came upon Maol Seachlainn's combined forces from the rear, and Maol Seachlainn fell in the resulting Battle of Ballyshannon.
Following Maol Seachlainn's death, Fitz Gerald installed Ruaidhrí Ó Cannanáin as King of Tír Chonaill. The latter, however, was later repulsed and slain by Gofraidh.
Maol Seachlainn is the subject of a contemporary elegy composed by Giolla Brighde Mac Con Midhe (died c. 1272).
