George Chandler is an independent scholar and genetic genealogy researcher. He is the administrator of the R-S1051 Project which is with Family Tree DNA. The families in the Mid Argyll Kinship group are in the R-S1051 haplogroup and are encouraged to also participate in George's project. The families with the R-S1051 all share the same paternal ancestor. Many of the families are from the mid Argyll area have a TMRCA that dates to 800AD to 1500AD. Some of the families in the R-S1051 group go much further back to the TMRCA, dating to Bronze Age Iberia. There are several Portuguese and Spanish families in the group that are the very distant cousins of the Mid Argyll Group families.

Below is the introduction to George Chandler's R-S1051 Project.
Recently many new SNP's have been discovered for this unique haplogroup which is located below DF13.
The majority of this family group have 5 main Patriarch SNP's (S1051, FGC9655, FGC9661, FGC9658 and FGC9657). The current age estimate for these Patriarch SNP's is approximately 3,200 to 4,500 years old and likely originated within what is known as the Bell Beaker culture. When examining other haplogroups of a similar age the S1051 people are very few by comparison.
Evidence suggests that the geographic origin of this family group could have been from what is now modern Scotland.

On the above spreadsheet links I've placed "SNP dates" which are an approximation as these mutation rates can vary. So far on average there is 1 Sanger SNP verified per 139 years so it's important to stress that these dates could change slightly as more research needs to be completed. There are instances like the single defining McCeney SNP which likely exceeds 200 years since it's mutation and other examples which were fewer than 139 years. Other factors to consider are the number of SNP's captured from the various sequencing types and the number of raw SNP's which are culled due to reliability issues. The age estimate 139 years per SNP was calculated by using known genealogy, full Y testing, Sanger verification, STR calculations and averaging the number of raw SNP's located below DF13. It's also important to understand that chronology of many of the SNP's (including the 5 main oldest ones) are still unknown.
For those in the Mid Argyle FGC17906 Group - they will find this valuable book written by Barry McCain interesting and worth the purchase.
The following link is to a 64 page paper written by Ronald Henderson that I recently discovered online. Although some concepts found within may stir debate within the historical or scientific community I believe it was well written and worth adding to project page.
