Show ContentsMacIsaac History, Family Crest & Coats of Arms

The ancient Dalriadan clans of Scotland spawned the name MacIsaac. It is derived from the personal name Isaac. The Gaelic forms of the name are Mac Isaac or Mac Iosaig, both of which mean son of Isaac. 1

Early Origins of the MacIsaac family

The surname MacIsaac was first found in Inverness, where one of the first records of the family was in 1476 when "the lands of Ardere in the barony of Clastray were resigned by Mariot, daughter of Molmoria M'Kesek." 1

Spelling variations for the family are quite varied: Mackessack, Mackissack, Mackissock, Mackissek, Makesaig (1592), Makkessake (1591), McKisack (1684) and many more.

In 1496, Donald Makessaig was recorded at Kilmun and he is probably the Donald McEsayg recorded in 1511. "John M'Intheir was convicted in 1623 for letting M'Keissik's 'bairnis the for hunger' in Breadalbane (BRT., p. 379 -there was probably a famine). Marion MacKissock was resident in the parish of Boyne, 1684, Elspet M'Kissick in Relliclone, parish of Madertie, 1658 (Dunkeld)." 1

MacIsaac Spelling Variations

In the Middle Ages, the translation between Gaelic and English was not a highly developed process. Spelling was not yet standardized, and so, an enormous number of spelling variations appear in records of early Scottish names. MacIsaac has appeared as MacIsaac, MacIsaack, Kissock and others.

United States MacIsaac migration to the United States +

Many settled along the east coast of what would become the United States and Canada. As the American War of Independence broke out, those who remained loyal to the crown went north to Canada as United Empire Loyalists. The ancestors of all of these hardy Dalriadan-Scottish settlers began to recover their collective history in the 20th century with the advent of the vibrant culture fostered by highland games and Clan societies in North America. Highland games, clan societies, and other organizations generated much renewed interest in Scottish heritage in the 20th century. The MacIsaac were among the earliest of the Scottish settlers as immigration passenger lists have shown:
