Hart History, Family Crest & Coats of Arms 

The Irish name Hart was originally written in a Gaelic form as O’h-Airt, which connotes a descendant of Art. 1

Specifically, the family claim descent through “Art Eanfhear, who is number 81 on the ‘Line of Heremon,” and son of the Monarch Conn of the Hundred Battles.” He was at times called “The Solitary,” as he was the only one of his father’s sons that survived; his two brothers Conla Ruadh and Crionna, having been slain by their uncles. His grief was so strong that in some writings, he was referred to as “Art, the Melancholy.” 2

The name literally means “a bear, a stone; noble, great, generous; hardness.” 3

Early Origins of the Hart family

The surname Hart was first found in County Meath (Irish: An Mhí) anciently part of the kingdom of Brega, located in Eastern Ireland, in the province of Leinster, where they were of the southern Ui Neill. Before the Anglo-Norman invasion of the 12th century, their chiefs were known as the lords of Teffia.
