Acknowledgments:  

Many thanks to Gene Stark, Sheila Schmutz, Lee Stark, and Gwen Boyer Bjorkman for their assistance and feedback.

Genetic Genealogy:  

Is the application of genetics to traditional genealogy and involves the use of genealogical data and DNA testing to determine the genetic relationships between individuals. (Click HERE for more information on DNA and Y-chromosome testing. (Use Back Button to return to this text.)

Part 1: Y-DNA Analysis of the Descendants of Aaron Stark [1608-1685]

The male Y-chromosome is handed down from father to son relatively unchanged through the generations. A comparison of the Y-DNA of two males with the same surname can determine their relatedness to each other. Groups of males with the same surname so tested and compared can define family groups and establish a probability they have a most recent common ancestor who lived within the last 20 generations. The usage of surnames did not become common until the 13th and 14th centuries. By the year 1500, surname usage had become common practice. Considering that one generation is about 25 years or more, then the year 1500 or before would be the approximate equivalent of about 20 generations prior to the present generations.

 

Part II: Genetic Genealogy Analysis of the Descendants of Aaron Stark [1608-1685]

All of the male individuals discussed in Part I of this report have been found to be descendants of Aaron Stark [1608-1685] of Connecticut.  The Genetic Results Table presented in Part I suggests there is a high probability these men all have a common ancestor who lived within the previous 20 generations. The genealogy of the participants suggests all of the members share Aaron Stark [1608-1685] as a common ancestor who lived within the previous 13th  generation relative to Member 98044 (Click HERE to see the Genealogical Lineage Table presented in Part I).

Part II will analyze the genetic results of those members having 37 marker haplotypes.

 

Appendix 1: Defining the Ancestral Haplotype of Aaron Stark [1608-1685]

The genealogical research suggests Aaron Stark I [1608-1685] was the common ancestor of all of the members in the genetic program. Using the Genetic Results Table and the Genealogical Lineage Table, the triangulation method devised by Charles F. Kerchner, Jr. will be employed to define the P37 Ancestral Haplotype of Aaron Stark [1608-1685]. (See Charles F. Kerchner, Jr.'s article entitled "Triangulation Method for Deducing the Ancestral Haplotype in Y-DNA Surname Projects.")

 

Appendix 2: Haplotype and DYS Marker Life Expectancy Calculations

Mutation Rate: The rate at which a genetic marker or haplotype mutates or changes over time; expressed as a decimal value or a percentage. Commercial DNA testing laboratories use an average haplotype mutation rate most often given as 0.002, 0.003, and 0.004. Depending on the study, these average mutations for all of the markers in a haplotype applies to the general male population as a whole.

Surname projects having genealogical research of high quality with one common ancestor identified as the progenitor  —  can have average mutation rates that do not agree with the literature.  The number of participants and the genealogy of the descendants of Aaron Stark [1608-1685] is of sufficient quality that it becomes possible to calculate the average mutation rate for various Haplotypes and DYS Markers.

 

Appendix 3: Summary of DYS Marker Mutations 

Summarizes the suggested allele values of the complete population of individuals reported in the Genealogical Lineage Table reported in Part 1.
