Sus armas: en campo de gules, un león pasante y guardante, de oro. En la base, un corazón humano, de plata. Cimera: un brazo desnudo, cortado debajo del codo, en posición levantada, esgrimiendo en la mano una espada en llamas, de su color.

Harte / O´Hart

El apellido Hart es inglés, pero lo que los portan en Irlanda (que por lo general lo escriben Harte) son descendientes del Clan O´Hart, en irlandés O'hAirt. Dice O'Hart que son de la línea de Heremon, descendientes de Art Eanfhear, hijo de Conn “of the hundred battles”, nº 80 en el pedigree de esa línea.

The names O'Hart, Hart and Harte in Ireland are derived from the native Gaelic O'hAirt Sept that was originally located in County Meath but which later located to County Sligo. Hart was also introduced into Ulster Province by settlers from England, especially during the seventeenth century.

Native English names, numerous in England but in Ireland the Harts (usually spelt Harte in Connacht ) are nearly all of the sept O'Hart. Some families have always retained, others have recently resumed, the prefix O. In Irish the name is O hAirt,Le. Descendant of Art, who was son of King Conn of the Hundred Battles. The O'Harts were of the southern Ui Neill and were one of the Four Tribes of Tara: in early times their chiefs were lords of Teffia (Co. Meath), but after the Anglo-Norman invasion they were pushed the barony of Carbury, Co. Sligo. O'Hart is included among the sixteenth century Sligo chiefs in the "Composition Book of Connacht ". Sligo, with the adjacent counties of Leitrim and Roscommon, is their principal home today though the name is also found in Co. Cork . The O'Harts of Newtown, Ardtarmon, and other extensive estates in Co. Sligo, were, until the seventeenth century, one of the leading families in north Connacht, but like other Catholic proprietors, were reduced to straightened circumstances by the two great confiscations of land in that century. The best known man of the name was John O'Hart (1824-1870), author of Irish Pedigrees: the Original Stem of the Irish Nation, a laboriously compiled and voluminous, but not always reliable, work. Therein will be found much information regarding the O'Harts of Co. Sligo.
