Show ContentsGan Surname History

Throughout history, very few Irish surnames have exclusively maintained their original forms. Before being translated into English, Gan appeared as Mac Cana, which is derived from the word cana, which means wolf cub.

Early Origins of the Gan family

The surname Gan was first found in County Armagh (Irish: Ard Mhacha) located in the province of Ulster in present day Northern Ireland, at Clanbrasil, a region on the southern shore of Lough Neagh.

The family supplanted the O'Graveys at the time of Strongbow's Anglo-Norman invasion in 1172 as lords of this area and became known as the Lords of Clanbrassil. One of the earliest records of the name was Amhlaibh Mc Canna (died 1155), described by the Four Masters as "pillar of chivalry and vigour of Cinel Eoghin" 1

United States Gan migration to the United States +

A great mass of Ireland's native population left the island in the 19th century, seeking relief from various forms of social, religious, and economic discrimination. This Irish exodus was primarily to North America. If the migrants survived the long ocean journey, many unfortunately would find more discrimination in the colonies of British North America and the fledgling United States of America. These newly arrived Irish were, however, wanted as a cheap source of labor for the many large agricultural and industrial projects that were essential to the development of what would become two of the wealthiest nations in the western world. Early immigration and passenger lists indicate many people bearing the Gan name:
