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:

White Wand (a symbol of authority).[11] They were the only other freeholders in Muskerry besides the O'Mahonys,[12] and had built several castles in their territories, including Carraignaneelagh, Drumcarragh and Carrignacurra, of which Carrignacurra is the only one still standing.[13] The celebrated Irish language writer Peadar Ua Laoghaire was a descendant of the Carrignacurra branch of the family.[14]

Donough MacCarty, 1st Earl of Clancarty did however appear to do his best to allow them to stay on their lands through leasing.[15] The family became much more scattered during the later Williamite War in Ireland
