Etymology of MacKennedy

What does the name MacKennedy mean?

The ancestors of the MacKennedy family lived among the Strathclyde-Briton people in the 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.

MacKennedy Coat of Arms Creation

The crest of the Clan Kennedy is a swimming dolphin, and Dauphin, the name given to the eldest son of the French kings, is a pun. The dolphin in heraldry is represented as the king of fishes, strong and swift in pursuing other fish, a lover of men and music, and was used to convey the idea of sovereignty. It is said that Ulysses carried a dolphin on his shield and signet ring, because that fish saved his son Telemachus when he fell into the sea.

David, the son of Sir Gilbert Kennedy, was one of the retinue which attended Margaret of Scotland on her marriage to the Dauphin in 1436, in honour of which the alteration may have been made to the supporters and crest. One of the family became Joan of Arc's most trussed generals, and it may have been because of this that the pun was made, dolphin for Dauphin. 1

Early Origins of the MacKennedy family

The surname MacKennedy 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.' 2

Migration of the MacKennedy family

Unrest, poverty, and persecution caused thousands to look for opportunity and freedom in the North American colonies. The crossing was long, overcrowded, and unsanitary, though, and came only at great expense. Many Strathclyde families settled on the east coast of North America in communities that would form the backbone of what would become the great nations of the United States and Canada. The American War of Independence caused those who remained loyal to England to move north to Canada as United Empire Loyalists. In the 20th century, Strathclyde and other Scottish families across North America began to recover their collective heritage through highland games and Clan societies. Among them: Alexander Kennedy settled in Charleston in 1763; Alexander Kennedy settled in Virginia in 1774; Angus Kennedy settled in New York in 1775; Hector Kennedy settled in Philadelphia in 1806.



The MacKennedy 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.
