Etymology of MacDevitt

What does the name MacDevitt mean?

The original Gaelic versions of today's Irish names demonstrate a proud, ancient past. The original Gaelic form of the name MacDevitt is Ó Dochartaigh, from the word "dochartach," which means hurtful or obstructive 1 and in this case, it would be termed as a nickname.

Early Origins of the MacDevitt family

The surname MacDevitt was first found in at Inishowen, in the barony of Raphoe, in County Donegal, where they were a large and influential sept, and were kin to the O'Donnells.

They were one of the principal Irish clans to resist the Norman invasion of 1170 and were known as the Lords of Innishowen directly descended from the distinguished Irish General King Niall of the Nine Hostages, who was descended from the Heremon line of Irish Kings.

The MacDevitts, who exist in large numbers in Inishowen, are descended from David O'Doherty, a chief of Cinel Conaill who was killed in 1208. Some members of the MacDevitt branch migrated to the territory of Oriel, now counties Louth, Monaghan, and south Down. There the "D" was aspirated creating the early Anglicization MacCaveat, and then the variation MacKevitt.

Expanding their territory, they came to rule the peninsula of Inishowen in the 14th century. However, the poorly-timed and disastrous rebellion against the English crown led by Sir Cahir O'Dougherty in 1608, drastically reduced the power of the once powerful sept.

"The O'Doghertys were a powerful Sept in County Donegal, and were located in Inishowen Barony, of which O'Dogherty was Lord. The Doghertys or Dohertys are numerously represented there at the present time." 2

MacDevitt migration to the United States +

Thousands of Irish families left for North American shores in the 19th century. These people were searching for a life unencumbered with poverty, hunger, and racial discrimination. Many arrived to eventually find such conditions, but many others simply did not arrive: victims of the diseased, overcrowded ships in which they traveled to the New World. Those who lived to see North American shores were instrumental in the development of the growing nations of Canada and the United States. A thorough examination of passenger and immigration lists has disclosed evidence of many early immigrants of the name MacDevitt:

The MacDevitt Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Ar Ndutcas
Motto Translation: Our heritage
