Áed in Macáem Tóinlesc Ó Néill

Áed in Macáem Tóinlesc (died 1177) founded O'Neill power in Tír Eogain. After High King Muirchertach Mac Lochlainn was killed in 1166, Áed was proclaimed king of Tír Eogain with the backing of Donnchad Ua Cerbaill.

In 1167 High King Ruaidrí Ua Conchobair divided the province between Áed and Niall Mac Lochlainn. As Ruaidrí's vassal Áed brought three thousand men to the 1174 siege of Norman-held Trim. He was killed by Máel Sechlainn Mac Lochlainn in 1177, leaving his son Áed Méith to entrench O'Neill rule.
