Introduction
Within genealogy circles, family stories of Native American1 heritage exist in many families whose American ancestry is rooted in Colonial America and traverses Appalachia. The task of finding these ancestors either genealogically or using genetic genealogy is challenging.
With the advent of DNA testing, surname and other special interest projects, tools now exist to facilitate the tracing of patrilineal and matrilineal lines in present-day people, back to their origins in either Native Americans, Europeans, or Africans. This paper references and uses data from several of these public projects, but particularly the Melungeon, Lumbee, Waccamaw, North Carolina Roots and Lost Colony projects.

The Melungeon Historical Society was formed in 2008 to promote factual Melungeon research and dispel the many myths and false statements found on the Internet about this intriguing group of dark skinned persons who lived in East Tennessee and nearby regions.

There is No Unique Turkish Genealogy
by Janet Crain
It is now quoted widely on the Internet that certain groups (American Indians and Melungeons) in the USA have "Turkish DNA". The article below from PubMed does not bear out that possibility. The suggestion is disingenuous at best.
The most important sentence in the article below is this:*The major components (haplogroups E3b, G, J, I, L, N, K2, and R1; 94.1%) are shared with European and neighboring Near Eastern populations* and contrast with only a minor share of haplogroups related to Central Asian (C, Q and O; 3.4%), Indian (H, R2; 1.5%) and African (A, E3*, E3a; 1%) affinity.
In other words, 94.1% of the DNA found in 523 Turkish Y chromosome samples is shared with European and neighboring Near Eastern populations. So there is no special motif or Turkish DNA. And this finding is explained by the closing sentence; "the variety of Turkish haplotypes is witness to Turkey being both an important source and recipient of gene flow".
Genes have flowed out and genes have flowed in for a very long time and cannot now be separated as belonging exclusively to one group or the other. So it is very deceptive to speak of "Turkish DNA" in the context of it being unique.

Analysis of 89 biallelic polymorphisms in 523 Turkish Y chromosomes revealed 52 distinct haplotypes with considerable haplogroup substructure, as exemplified by their respective levels of accumulated diversity at ten short tandem repeat (STR) loci. *The major components (haplogroups E3b, G, J, I, L, N, K2, and R1; 94.1%) are shared with European and neighboring Near Eastern populations* and contrast with only a minor share of haplogroups related to Central Asian (C, Q and O; 3.4%), Indian (H, R2; 1.5%) and African (A, E3*, E3a; 1%) affinity. The expansion times for 20 haplogroup assemblages was estimated from associated STR diversity. This comprehensive characterization of Y-chromosome heritage addresses many multifaceted aspects of Anatolian prehistory, including: (1) the most frequent haplogroup, J, splits into two sub-clades, one of which (J2) shows decreasing variances with increasing latitude, compatible with a northward expansion; (2) haplogroups G1 and L show affinitie s with south Caucasus populations in their geographic distribution as well as STR motifs; (3) frequency of haplogroup I, which originated in Europe, declines with increasing longitude, indicating gene flow arriving from Europe; (4) conversely, haplogroup G2 radiates towards Europe; (5) haplogroup E3b3 displays a latitudinal correlation with decreasing frequency northward; (6) haplogroup R1b3 emanates from Turkey towards Southeast Europe and Caucasia and; (7) high resolution SNP analysis provides evidence of a detectable yet weak signal (<9%) href="http://www.ncbi.nlm.nih.gov/pubmed/14586639">http://www.ncbi.nlm.nih.gov/pubmed/14586639
