Bridging the Atlantic to find lost English, Scottish or Irish ancestors.
There is a good likelihood of being able to localise where your ancestor came from using Y-DNA testing, thereby adding a whole new chapter to your origins. The Y chromosome is that part of the genetic structure which determines maleness, and passes unchanged from father to son, excepting that small random copying errors can occur. Y-DNA can be used as a genetic clock. Not only can it be used to find where your ancestors lived in England, Scotland or Ireland, it can also take the history of your surname back thousands of years before the surname even existed.

Quick Facts
- Y-DNA acts like a genetic clock, reaching back thousands of years
- Y-DNA is not included in standard tests from AncestryDNA
IN DEPTH
Y-DNA
There is a good likelihood of being able to localise where your ancestor came from using Y-DNA testing, thereby adding a whole new chapter to your origins. The Y chromosome is that part of the genetic structure which determines maleness, and passes unchanged from father to son, excepting that small random copying errors can occur. Y-DNA can be used as a genetic clock. Not only can it be used to find where your ancestors lived in England, Scotland or Ireland, it can also take the history of your surname back thousands of years before the surname even existed.
This type of DNA is not tested by ancestry.com. Our recommended provider for Y-DNA testing is familytreedna.com, based in Texas. Scroll to Paternal Ancestry and select one of their three products: Y-37, Y-111 or Y-700. These cost between $100 and $400. We particularly recommend the Y-700 because it provides the best possible resource. Familytree.dna will provide you with some interesting information, but it is unlikely that they will get your ancestors to a specific geographical location in the British Isles or Ireland. Having obtained your result, IHGS will then be ready to assist you.
Because the Y-chromosome follows a surname, it can only be used to answer questions about the surname with which it is connected. If you are a woman you need to persuade your father, brother, cousin or uncle to take the test on your behalf.
