What do you mean by ethnic? do you means origins? Have you tried Y (male line,surnames)DNA through a surname web-site such as www.one-name.org
I expect to find north europeans with my surname.
May I ask what surnames are you researching? My grandparents surname is Heilig which is a german surname and my grand dad is multi racial.
If someone sends you info regarding a site, please let me know.
Thanks so much.
