Note to following Clan 1 "Proposed Lineage Tree":
My (J.P. Childress) Overton Lineage has been verified by use of Y-DNA. I constructed the following family tree using the results of DNA testing on participants in the FamilyTreeDNA project.
The following chart represents a proposed lineage that might possibly exist, given the known documentation of each of the Participant's line and the Y-DNA results of the six Overton DNA participant (as of July 1, 2009). Perhaps the only significant contrary finding is the Y-DNA "signature" of Alton Lee Overton (1933-2000). His DNA reflected a three step mutation compared to the probable M.R.C.A. (most recent common ancestor) Y-DNA alleles values. While this occurrence is not impossible, it is somewhat improbable. However, Alton Lee's closest "documented" cousin, Donald Ray Overton (b. 1945) has a much closer alignment with the MRCA alleles values, so perhaps Alton's Y-DNA (and that of his immediate ancestors) did, in fact, mutate in an unusually rapid fashion.
In any event, the reader should accept the following as only a proposed chart and should strive to find documentation that will either validate or invalidate these findings. (J.P. Childress - July 2009)
Note: Chart updated with new findings and alignments as of October 11, 2009. In this new alignment, Alton Lee and Donald Ray Overton lineages were placed under the David Overton, b. 1765, the son of Aaron Overton (earlier lineage was under David Overton, son of John Overton, Sr. b. 1720).
Note: In the chart above, similar background colors indicate proposed brothers.
Note: The above data is merely a proposed lineage relationship chart between the Overton DNA Project participants, based on their respective Y-DNA test results as of 7/30/2009. Kevin G. Overton’s final results are not yet available as of this date. A potentially difficult fact to explain is that Alton Lee Overton’s results reflected a three single step mutation against the proposed baseline which seems to indicate a low probability of having the ancestry as this chart indicates. Extended marker analysis likely will be the only way in which a more concrete lineage chart can be constructed, along with pertinent documentation, of course. Donald Ray (36590) and Kevin G. (150858) both have 37-marker tests; the other participants have only 25-marker tests.
