DNA Project notes
& Other Variations



1) Identify others who are related
2) Prove or disprove theories regarding ancestors
3) Solve "brick walls" in your research
4) Determine a location for further research
5) Validate existing research
6) Develop a DNA database for future researchers

Most surname projects begin with the objective to identify others who are related; throughout the project other objectives are achieved as a result of the project.

Although more documentary evidence remains to be found, traditional genealogical research may never find all the connections between the various lines. In addition, there are undoubtedly links that have been made that are not correct. The availability of Y chromosome analysis now provides a new way to determine direct male to male lineage, and this is the basis of this project. An analysis of the mutations in the Y-chromosome can also be used to estimate the "Most Recent Common Ancestor (MRCA)" in terms of number of generations since the separation occurred. If your research has hit a "brick wall," DNA analysis could be the breakthrough you have been looking by finding connections to other family lines.

Our Surname DNA Project may help answer these questions:

How many different common male ancestors are associated with the surname?
How are the different lines related?
Are your ancestors related to other lines?
Are all lines related or are there many different family lines?
Can connections be made between lines in Ireland, Scotland, England, the United States and other countries?
Which researchers should be collaborating because they share a common ancestor?


There is always a chance there was an unknown adoption, infidelity, etc sometime in the past. That is why it is desirable to have two or more males who are distant cousins tested for each known line to prove the line to a common male ancestor and establish the genetic identification of that line. Be sure to read False Paternal Events in the DNA Project Notes. If you know that you, or an earlier ancestor with your surname, were adopted into the family, you do NOT want to participate in a project for your legal surname because you carry a different Y chromosome.

And, of course, errors in your research may be the cause of unexpected test results.
