John O'Hart (Irish:Seán Ó hAirt; 1824–1902) was an Irish historian andgenealogist. He is noted for his work on ancient Irish lineage.
He was born inCrossmolina, County Mayo, Ireland. A committedRoman Catholic andIrish nationalist, O'Hart had originally planned to become a priest but instead spent two years as a police officer. He was anAssociate in Arts at theQueen's University, Belfast. He worked at the Commissioners of National Education during the years of theGreat Famine. He worked as a genealogist and took an interest in Irish history. He died in 1902 inClontarf nearDublin, at the age of 78.
O'Hart's 800-page,The Irish and Anglo-Irish landed gentry (Dublin 1884), was reprinted in 1969, with an introduction byEdward MacLysaght, the firstChief Herald of Ireland. Another work,Irish pedigrees; or, The origin and stem of the Irish nation, first published in 1876, has come out in several subsequent editions.[citation needed]
To complete his genealogies he used the writings ofCú Choigcríche Ó Cléirigh,Dubhaltach Mac Fhirbhisigh and O'Farrell, along with theAnnals of the Four Masters, for the medieval pedigrees. He used the works ofBernard Burke, John Collins and others to extend his genealogies past the 17th century.[citation needed]
In hisIrish Pedigrees, O'Hart presents the legendary origins of the Irish people, from the Biblical Adam and Eve through the kings of ancientIreland. Irish tradition holds that every Irish person is descended from the kingMilesius who emigrated fromSpain in approximately 1700 BC, according to theAnnals of the Four Masters. O'Hart started each of his genealogies withAdam, recording Milesius as his 36th descendant.

According to O'Hart's account,Milesius had four sons,Heber, Ir,Heremon, andAmergin, who were involved, with their uncle Ithe, in the invasion of ancientIreland;Milesius, himself, had died during the planning. Amergin died during the invasion, without issue.[citation needed] It is from the four other invaders —Heber,Ir,Heremon, andIthe — from whom the Irish are alleged to descend. These, according to O'Hart, are the four lines from which all true Irish descend.Conn of the Hundred Battles was a descendant of Erimon, andBrian Boru was descended from both Heber and Conn.[citation needed]
