The name MacKenneday was first used by a Strathclyde-Briton family from the Scottish/English Borderlands. It was 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 MacKenneday family

The surname MacKenneday 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

Migration of the MacKenneday family

Unwelcome in their beloved homeland, many Scots sailed for the colonies of North America. There, they found land and freedom, and even the opportunity to make a new nation in the American War of Independence. These Scottish settlers played essential roles in the founding of the United States, and the shaping of contemporary North America. 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 MacKenneday 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.
