Etymology of Hennedy

What does the name Hennedy mean?

The saga of the name Hennedy begins with a Strathclyde-Briton family in the ancient Scottish/English Borderlands. It is a name for a dour or serious person. Further research revealed that the name is derived from the Gaelic nickname Cinneididh, which translates as grim-headed. It is doubtful that there is any ancient relationship between the Irish Kennedys and the Scottish Clan.

The Irish Kennedy's history dates back to about 900 AD, and there did not appear to be any direct relationship between the two families. However, in the 16th century, a sept of the Scottish Kennedy Clan did develop in Ulster, but they are undoubtedly migrants from Scotland, and had no previous link to the southern Irish Kennedys.

Early Origins of the Hennedy family

The surname Hennedy was first found in Ayrshire (Gaelic: Siorrachd Inbhir Àir), formerly a county in the southwestern Strathclyde region of Scotland, that today makes up the Council Areas of South, East, and North Ayrshire, where the earliest record of them dates from 1185, during the reign of King William the Lion, when a Henry Kennedy was reported to have been involved in a rebellion in Galloway but died in battle.

The Kennedys derived from a branch of Celtic Earls of Galloway (not to be confused with Gallway, which is in Ireland). Their power and influence in that region was great. In fact, there is a rhyme handed down through clansmen and bards from the year 1300 which runs as follows: 'Twixt Wigtown and the town of Ayr, Portpatrick and the Cruives of Cree. No man need think to bide there, unless he court with Kennedy.' 1

Hennedy Spelling Variations

Spelling and translation were hardly exact sciences in Medieval Scotland. Sound, rather than any set of rules, was the basis for spellings, so one name was often spelled different ways even within a single document. Spelling variations are thus an extremely common occurrence in Medieval Scottish names. Hennedy has been spelled Kennedy, Kannady, Kenardy, Kennaday, Kenneday, Kenneyday, Kennediem, MacKennedy, MacUalraig (Gaelic) and many more.

Hennedy migration to the United States +

Such hard times forced many to leave their homeland in search of opportunity across the Atlantic. Many of these families settled along the east coast of North America in communities that would become the backbones of the young nations of the United States and Canada. The ancestors of many of these families have rediscovered their roots in the 20th century through the establishment of Clan societies and other patriotic Scottish organizations. Among them:

Hennedy Settlers in United States in the 19th Century
  • Patrick Hennedy, who arrived in San Francisco, California in 1850 2

Contemporary Notables of the name Hennedy (post 1700) +

  • Roger Hennedy (1809-1877), Irish botanist, born in August 1809 at Carrickfergus, near Belfast, but was of Scottish extraction, his father being descended from the Kennedys of Ailsa Craig, Ayrshire, who changed their name to Hennedy in Ireland 3


The Hennedy 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: Avise la fin
Motto Translation: Consider the end.
