About us


Surname DNA testing is the newest tool available to genealogists!

•Surname tests allow genealogists to verify their father's father's...father's paternal ancestry.

•Surname DNA information can be very powerful when combined with traditional paper trails.

The Downey/Downs/Downie/Dowie DNA Project DNA Project is open to all the DNA Project families, of all spelling variations, and from all locations. (If your surname is not included please contact the Project Administrator.)

Participating in a Surname DNA Project provides:

•The participant's genetic DNA, which is very close (and sometimes identical) to his earliest known ancestor.

•The participant's "deep" ancestry (Haplogroup), which identifies the paternal ancestor's prehistoric origins.

•A sense of camaraderie, which is particularly strong for those who share a genetic ancestry.

•Stimulation to family research and renewed sharing of information.

•A wider sense of identity and relationship, as we begin to realize how much we are a World Family.

•A chance to compare your genetic ancestry with those of your Surname and the spelling variations.

•Your genetic matches who do not share your common surname.

•The knowledge to understand our ancestors better - particularly where the records have been lost.
