Last Name O-doherty

What is the origin of the last name O-doherty?

The surname "O'Doherty" is an Irish Gaelic name, derived from the Old Gaelic "Ó Dáoraidh" which translates to "descendant of Dáiredach." The name "Dáiredach" was a common personal name in pre-Christian Ireland. The O'Dohertys were originally a powerful sept, or clan, located in County Donegal. Their territory was known as Tir Conaill, and the O'Dohertys ruled this region for over 1000 years until they were displaced during the 17th-century plantations of Ulster by English settlers. The prefix "O" or "Mac" (pronounced "oh" or "mak") in Irish surnames indicates a male lineage; in this case, O'Doherty means a descendant of Dáiredach. The name is still common among the Irish and Irish diaspora worldwide.

The meaning and origin of the last name O-doherty

The surname O'Doherty is an Irish patronymic name derived from the Gaelic "Ó Dochartaigh", which means "descendant of Dochartach". The name was commonly anglicized as Doherty, Dougherty, or Dockerty in English. The Dohertys were a prominent sept (clan) in County Donegal and part of Inishowen in the Province of Ulster, Ireland. They were chieftains of Tir Conaill, one of the five kingdoms of Gaelic Ireland. Notable members of the O'Doherty clan include Saint Colmcille (521-600 AD), who was born into the family and is considered the patron saint of Ireland, and Hugh O'Doherty, who was the last Gaelic chieftain of Inishowen before the area came under English control in the 17th century. The name spread to other parts of Ireland and the British Isles, as well as North America and Australia due to emigration.
