Our ARTERBURN Y-Haplogroup (SNP) is currently identified by the subclades
of R-Y47 and R-Y46 (see YFull Tree below). R-Y46 is our downstream terminal
SNP, or the most recent public SNP or subclade that we share with other individuals
who have also tested positive for this same Y-SNP. These particular Y-SNPs are
not displayed on our project's SNP page, since only a limited number of SNPs can
be displayed from among thousands— both positive and negative, public (shared)
and private (personal)— in the test results of our Big Y participant (343708), who
is a direct descendant of both William Arterburn Sr. and of William Arterburn Jr.
The display of "Haplogroups"— or subclades within Haplogroup R1a, actually—
for ARTERBURN descendants who have been tested in our Project differs on
the DNA Results chart provided by FTDNA because of changes in the assignment
of established subclades of Haplogroup R since testing for each descendant
was completed, which conformed to FTDNA's business model and software
revisions. In effect, the display of Haplogroups on the DNA Results chart
page should be disregarded until such time as FTDNA has corrected this.
None of these differences in display reflect uncertainty or disagreement about
the ARTERBURN Haplogroup (attested also by direct query to the president of
FTDNA). Our Big Y test results has confirmed all SNPs that identify our branch
of subclades within Haplogroup R thus far to R-Y46. Big Y has also yielded
additional positive SNPs that may result in future matches and in new and more
recent subclades that will further refine our Y-Haplogroup, as the trail of our
ancestors through the Old World to the New is disclosed. Each new positive
SNP match (subclade) represents a shared or common genetic ancestor, and
also a new and more recent relative(s) with whom we share that common
ancestor. While these ancestors will not be personally identifiable, we may
be able to locate them in a particular region, ethnicity, or culture, subject to
further refinement and clarification as time goes on.
An alphanumeric nomenclature (e.g., R1a1a1b2a2a) with corresponding numbers
of one or more associated Y-SNPs (e.g., Z2123) has been used to identify the
proven to be more congenial to an uncluttered and easy to read display, as
alphanumeric extensions can appear bewildering with the increase of subclades
among all Haplogroups.
For convenience, the ARTERBURN Y-DNA PROJECT will use only the Y-SNP
number (e.g., R-Y46) to designate our currently or most recently identifiable
subclade in Haplogroup R, as illustrated by the Y-DNA Tree of YFull, and as
new subclades may be established for ARTERBURN in the future.
The individuals with whom we share Y-SNPs R-Y47 and R-Y46 are either living
in South Asia or are South Asian emigrants living abroad. Gujarati, Sri Lankan
Tamil, Telugu, and Bengali ethnic or ethnolinguistic groups are represented.
Thus, we share common ancestors with these folks who have tested positive
for R-Y46 and R-Y47.
The current estimate of the time frame for the most recent common ancestor
(TMRCA) for R-Y46 is approximately 3,100 years before present (ybp). This
estimate of TMRCA may change in the future as Y-DNA testing continues and
if new SNP matches occur, and as STR comparisons of such new matches are
made. Our most recent common ancestor may advance into a more recent
time frame as we discover new matches for ARTERBURN Y-DNA of both SNPs
and STRs in the future.
These test results match the historical evidence found in America
within the past 300 years: A physical description of Peter Arterburn
accompanied by credible attestation in court testimony in Tennessee
that Peter's patrilineal ancestors "came from the East India;" an
apparent linkage of Peter by name (i.e., "alias Williams") to one or
more individuals identified as "[East] Indian" in court records in
Maryland; and various other independent references to an "Indian"
heritage for ARTERBURNS in Virginia, Tennessee, and Kentucky
(see Some Research Notes (7th ed.), Supplemental Notes, and
the "News" page).
