Who: Open to any male (because only males have Y-DNA) whose surname is Mackay - or a variation, including but not limited to McKay, McCoy, McKoy, McKee, McKie, Kies. Y-DNA is passed from father to son, so a woman who wants to know her family results should get her brother, father, paternal uncle or male cousin to participate.
Why: Y-DNA testing provides clues to your deep ancestral and geographic origins. It can help you find relatives who share a common ancestor, even though your genealogy research hasn't found the link. Testing can also confirm the results of your genealogical research. Even if you think you know your ancestry, you may be able to help other participants find their ancestral home.
How; Join the Mackay Surname Project at FamilyTreeDNA or submit your results from any other DNA testing company. Testing is done with a simple cheek scraping and results are sent to you and to the project. There is a discount for testing as part of a surname project. Contact the Project Administrator for suggestions on how to participate for the lowest cost.
MtDNA: Many of the project participants have chosen to have their mtDNA tested too. MtDNA follows the maternal line, so men and women can participate in this test.
