Haplogroup T

The results for Kit #65009 were originally posted at FTDNA as Haplogroup K2 but are now showing as Haplogroup T

ENGLAND - R1a

The England group and the Captain Francis Drake group both belong to the R1a haplogroup and thus share a common heritage.  However, the closest match between the two groups differs by 10 genetic mutations.  The FTDNA Time Predictor estimates a 96.55% probability that the donors share a common ancestor withing 48 generations, indicating that the common ancestor likely lived before the year 1000AD.

CAPTAIN FRANCIS DRAKE - R1a

Captain Francis Drake is the earliest of the EKAs in the R1a, American Continent, grouping and may be the common ancestor of this entire group.  The two descendant donors for Captain Drake used two different companies to process their samples: FamilyTreeDNA(FTDNA) for kit #7895 and DNA Heritage(DNAH) for kit #YSC1835.  Since the two companies examine different markers, we can only compare on 32 markers and the two donors match on 31 out of the 32.  Kit# 7895 (FTDNA) has a one step mutation on DYS 447 (26 rather than 25 which is more common among this group).  This mutation my be recent like the mutation on DYS 389-2 for Kit #2859, Elijah Drake in the Tennessee group below, and therefore insignificant.  If so, then we may get more meaningful results if we use the DNAH kit (YSC1835), but that result is missing the five markers indicated by dashes in the result table below.  If we make the assumption that those five markers match the FTDNA results, then using the DNAH test yields perfect 37/37 matches for Abraham Drake of Tennessee (2855), William Drake of Maryland (21915) and Lewis Drake (38531) & Benjamin Drake (17904) both of Virginia.  Using this 37/37 match, the FTDNA Time Predictor estimates that there is a 99.33% chance that the donors for the kits listed share a common ancestor within 12 generations.  That probability drops to 97.45% if we include the one-step mutation on Kit #7895.  Note: The donor for FTDNA Kit#7895 and Cpt. Francis Drake are separated by 12 generations.

Except for Samuel Drake of Mifflin Co., PA, John A. Drake of Alabama and Benjamin Drake of Davidson Co., TN, the EKAs provided in this section are all sons of Benjamin Drake who died in Carter County, TN in 1827.  Notice the mutations on DYS 389-2.  Since documentation exists supporting each donors descent from the EKAs given, we can be reasonably certain that the mutations are recent and therefore insignificant.  Since the results for Kit #2855, EKA Abraham Drake, do not contain any of the recent mutations, we are using this test to compare Benjamin Drake's line with the other R1a subgroups.  John A Drake is the great grandson of Abraham Drake.

Although contemporaries, we do not know if Benjamin Drake of Carter Co., TN and Benjamin Drake of Davidson Co., TN were related.  The 12 marker DNA results do tell us that the descendant donors for both men have a 55.88% chance of sharing a common ancestor within the previous eight generations.

Samuel Drake of Mifflin Co., PA may be a close relative to the family of Benjamin Drake of Carter Co., TN.  Both families lived in the same area of Pennsylvania in the mid to late 1700s.  However, we need to see results from a higher resolution test to strengthen that possibility.  Again, there is a 55.88% probability of a common ancestor within eight generations.
