The Huxford/Wiregrass Georgia DNA Project http://www.huxford.com/Genetics_Wiregrass
is a Regional DNA Project and is for living descendants of the pioneers of the Wiregrass area of Georgia and the neighboring area of northern Florida.
Wiregrass Georgia is the region in southeast Georgia that includes the current counties of Appling,Atkinson, Bacon, Ben Hill, Berrien, Brantley, Brooks, Camden, Charlton, Clinch, Coffee, Colquitt, Cook, Echols, Glynn, Irwin, Jeff Davis, Lanier, Lowndes, Pierce, Thomas, Tift, Turner, Ware, Wayne, Wilcox and Worth.
The northern Florida counties in close proximity to the Wiregrass Georgia region (commonly referred to as the Suwannee Land) is where many of the descendants of the early Wiregrass pioneers migrated. The Florida Suwannee Land counties are: Alachua, Baker, Bradford, Clay, Columbia, Duval, Gadsden, Hamilton, Jefferson, Lafayette, Leon, Madison, St. Johns, Putnam, Suwannee, Taylor, and Union.
This project is for the purpose of supporting the genealogical efforts of the descendants for all the many pioneer families who settled the Wiregrass Georgia Region. Many surnames were changed during the 18th, 19th and early 20th centuries due to adoptions, out-of-wedlock births, family disagreements, etc. Therefore, the Y-DNA for many descendants may not match other descendants with the same surname. This project will permit comparisons of Y-DNA test results across the spectrum of Wiregrass families in conjunction with the use of the Wiregrass Family Database maintained by Robert B. Noles and the resources of the Huxford Genealogical Library. The Wiregrass Database contains the published genealogies (and a lot more) from the Folks Huxford and the Huxford Genealogical Society publications. The Wiregrass Georgia Regional DNA Project is open to anyone who believes they are (or could be) descendants of one of the area’s pioneer families. This project is both a Y-Chromosome (direct paternal line) and a mitochondrial DNA (direct maternal line) study. You are hereby cordially invited to participate in this historic project. Those requesting participation are requested to supply Robert B. Noles with their known genealogies.
