Migration of the McCellach family

Most of the Boernician-Scottish families who came to North America settled on the eastern seaboard of what would become the United States and Canada. Families who wanted a new order stayed south in the War of Independence, while those who were still loyal to the crown went north to Canada as United Empire Loyalists. In the 20th century, the ancestors of these families have gone on to rediscover their heritage through Clan societies and other patriotic Scottish organizations. Research into the origins of individual families in North America has revealed records of the immigration of a number of people bearing the name McCellach or a variant listed above: James Kellock, who was a servant, who arrived in Virginia in 1661; Alice Kellogg, who came to Hartford, CT in 1637; Daniel Kellogg, who arrived in Connecticut in 1651.
