in the 7th century. The port of Dún Laoghaire, near Dublin is not associated with the O'Leary sept(s), rather it is named for Lóegaire mac Néill, a 5th-century High King of Ireland. The book of Lecan (A.D. 1397-A.D. 1418) details the early status of O'Leary as a Corco Laide ''taisach duchusa'' (hereditary chieftain) in the tuath of Ross (Ruis), with associated families:

Tuath Ruis .i. Tuath in Dolaich, o Loch in Bricin co Faid Ruis -, o Thraig Long co Sid na Fear (i) Find. O Leagaire a taisach duchusa. Is iad so an oclaid duchusa .i. O Ruaidri -, O Lonan -, O Laidid -, O Torpa -, O hUrmoltaich -, O Mirin -, O Meic Dairic -, O Tuaraide -, O Trena -, O hUainidi -, O Cerdin

The name also occurs in the Cineal Laoghaire branch of the Eoghanacht dynasty which later came to dominate Munster. With the unrelated Corco Laidhe and Eoghanacht branches of O'Learys settling in north-west Cork and nearby Kerry respectively, the tracing of lineage is complex.
