O'Hennis History, Family Crest & Coats of Arms
- Origins Available:
The name O'Hennis is derived from the Gaelic "hAonghuis," a variant of "hAonghusa," which became O'Hennessy. Thus bearers of this name come from the same stock as the O'Hennesy Septs of Moyfenrath barony in Meath, and Philipstown barony in County Offaly. These Gaelic names mean 'the son of Angus,' and this distinguished Irish sept traces its origin back to King Laeghaire Lorc who reigned in 593 A.D.
Early Origins of the O'Hennis family
The surname O'Hennis was first found in County Kildare and the adjoining areas in Meath and Offaly, where bearers of the name have been found since the 16th century, when Irish names were being Anglicized.
"Ennis was formerly O'Hennis, which is Ó hAonghuis in Irish. In both those areas we find Ennis, then written Enos, Ennous (to mention only two of the many variants) very frequently in sixteenth century records."
