TERRY - LINEAGE GROUP 4 - Discussion
Haplogroup G2a
(This is of course a
work in progress)
Individuals in this group who have DNA tested as of April 25, 2007: T-19 and T-39 have ordered kits.
Two individuals who have tested are linked to William Terry of Botetourt County, Virginia through his son Jasper Terry m (1) Mary Morrison one of the 8 children of William Terry of Botetourt. The persons in this group are distinct in that their haplogroup G2 is rare among Europeans. From this information alone you can definitely say they are not related to the Southside Virginia Terry men in Group 1 in the study [haplogroup I1b] nor the northern branches of Terry men out of early Long Island, New York even though they have only tested 12 markers. It appears from the DNA tests as of June 07, 2007 Jasper Terry is unrelated to descendants and/or ancestors of John Terry and Esther Brown.
There is quite a bit on the family of Jasper Terry and son Josiah Terry and Descendants in of Terry and Allied Families Volume I and II by Frances Terry Ingmire rev 1983.
In light of recent DNA results please read pages

So early descendants of this
Terry family can be found in Virginia, Kentucky, Missouri, Indiana, Illinois, Tennessee and
Texas.
The genetic distance of 3 between T-19 and T-39 utilizing 67 markers indicates they are "related". However, the results are probably closer than the markers suggest due to mutations occurring after 1780. In fact, in a deposition in Hardin County, Kentucky chancery records, dated September 18, 1841 in the case of Blight vs. Anderson. John S. Terry, a surveyor, stated Jasper Terry, Sr. was his "Uncle". -- Therefore Jasper Terry b 1777 and and Aaron Terry b 1782 were brothers. Source: Terry and Allied Families, Volume II, page 36 by Frances Terry Ingmire, rev 1983. I do not have a copy of the deposition and have not had contact with Frances T. Ingmire in 3 or 4 years now.
As more males test in this group we will probably see a more clearly defined modal group.
| In comparing 67 markers, the probability that T-19 and T-39 shared a common ancestor within the last.... | |||||
| 4 generations | 8 generations | 12 generations | 16 generations | 20 generations | 24 generations |
| 21.88% | 66.05% | 89.73% | 97.48% | 99.46% | 99.89% |

*The above numbers are based exclusively on the comparison of their Y-DNA results, which show no mismatches. I believe a generation is considered to be 25 years. |

The FTDNATiP results are based on the mutation rate study
presented during the 1st International Conference on Genetic Genealogy, on
Oct. 30, 2004. The above probabilities take into consideration the mutation
rates for each individual marker being compared.
