Show ContentsIzaitch History, Family Crest & Coats of Arms

The Hebrides islands and the west coast of Scotland are the ancestral home of the Izaitch family. Their name comes 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 Izaitch family

The surname Izaitch 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

Izaitch Spelling Variations

Medieval translation of Gaelic names could not be referred to as an accurate process. Spelling was not yet standardized, and names in documents from that era are riddled with spelling variations. Izaitch has been written as MacIsaac, MacIsaack, Kissock and others.

Migration of the Izaitch family

Ancestors of many of the Dalriadan families who crossed the Atlantic still live along the east coast of the United States and Canada. Some Scottish settlers arrived in Canada during the American War of Independence as United Empire Loyalists, while others stayed south to fight for a new nation. The descendants of Scottish settlers in both countries began to rediscover their heritage in the 19th and 20th centuries through Clan societies and highland games. An inquiry into the early roots of North American families has revealed a number of immigrants bearing the name Izaitch or a variant listed above: Murdoch McIsaac who settled in New England in 1685; Malcolm MacIsaac settled in New York in 1775. In Newfoundland Dougal MacIsaac settled in Sandy Point in 1870.
