Hello McKaig descendants,

We would like to extend an invitation to join us in the McKaig surname project at Family Tree DNA One of the goals of our project is to understand how the various McKaig lines in America and Canada are related.

While the specific goals and objectives for each of our participants may vary, we are all interested in gaining answers to genealogical questions that cannot be answered through conventional research. DNA is a very powerful tool and, when used in conjunction with paper trail evidence, it can provide us with answers to some very important questions. DNA can tell us whether or not two or more poorly documented McKaig families, living in the same area at the same time, are related. It can also bring surprising results, such as connecting two McKaig lines that were before believed to be unrelated. A number of our participants have hit a brick wall in the mid-1800s. For those participants, matching DNA with someone who can trace his lineage back to the 1700s or even 1600s is an incredible gift.

The McKaig Clan is believed to have originated in the middle sections of Scotland and early McKaig families migrated to and from Northern Ireland. Later migrations took them to Colonial America around the mid 1700s, Canada in the early 1800s, Australia, England, etc.

The McKaig surname in the U.S. is a very rare one with a ranking of 28,283. McKaig is a variation of MacKaig. Other variations include: McCaig, MacCaig, McCague, MacCague, etc. The McKaig surname is an Anglicized or English form of the Gaelic MacThaidhg/MacTaidhg, meaning "son of TADHG". Variants of TADHG are: Tighe, Teigue, Teige, Teague (Irish), Tadg (Scottish). The commonly accepted meaning of Tadhg or Tadg is "poet" or "storyteller".

In the 1700s, McKaigs were primarily in Pennsylvania. By the 1840 U.S. Census, larger groups of the McKaig Clan could be found in Ohio and Maryland. In the 1841 Scotland census the McKaig surname is found largely in Dumfriesshire, Argyll, Kirkcudbrightshire, Lankarkshire, Renfrewshire. In the 1901 Irish census, the McKaig surname is found in these counties: Antrim, Cavan, Down.

Whatever your connection to the McKaig surname, you will likely benefit from DNA testing. For questions about how to join the project or how it can help you with your research, please email
