About us
The Y-DNA results are located under the DNA Results tab in the "Classic" and "Colorized" pages. The individual tests are grouped by the project administrator into different subgroups.
Each individual member's kit is organized by their haplotype, based off of their STR results and predicted or confirmed SNPs. If you are matched with other project members in a subgroup, than you all share a common ancestor at some point in time.
Check to see if your matches have a family tree uploaded, or contact them directly for more information. Some matches may be within a genealogical time frame and finding a common ancestor in paper records is a possibility.
Each subgroup is defined by their haplogroup. The list of SNPs in each subgroup heading is a short-hand descendancy chart from an ancient shared ancestor down to more recent times. As more project members take the Big Y700 test, more SNPs will be discovered and added to the phylogenetic tree. Some of the subgroups have had enough SNP testing done to bring their haplogroup (or terminal SNP) down into recent genealogical times. At least two or three Big Y testers are recommended for every subgroup in the project.
As with other surname projects, there are many unique and distinct paternal lines that make up the McDuffie diaspora. Since the origin of the surname around 1000 years ago, the surname was a mark of affiliation to a group or clan of families living in close proximity and with a perceived shared destiny. Not all of the males in the group or clan would necessarily have shared the same male ancestor at the time of surname adoption. Also, clans often absorbed other non-genetically linked groups as they expanded. Over the years this leads to many genetically separate lines with a common surname.
