I know of one ydna result from one of the projects I am a member of, The C/C3 project. There is a James Andrew Savoy, b. c. 1880, New Jersey, NB, Canada. His haplogroup is C3, but looking at the values, I am sure it is C3b like mine. C3b is only Native American. This person may be a case like mine where why surname was adopted. My ancestry is Mi'kmaq.
