About us


Our ARTERBURN Y-Haplogroup (SNP) is currently identified by the subclades  

of R-Y47 and R-Y46 (see YFull chart 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-SNPThese 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 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.


[Note:  The display of the "Haplogroup" —or subclade within Haplogroup R,

actually— for ARTERBURN descendants who have been tested in our Project 

differs on the DNA Results chart (R-Z93, R-M417, R-M512) provided by FTDNA

because of changes in the parameters for assigning subclades of Haplogroup R 

since testing for each descendant was completed, which conforms to FTDNA's

business model.  Our Big Y participant has temporarily been assigned the larger 

and more inclusive clade of R-M417 (R1a1a1) because FTDNA's comprehensive 

Big Y SNP testing program has created the potential for future SNP matches

and new subclades yet to be established that would more fully uncover our

genetic line of descent to William and Peter. 

None of these differences in display reflect uncertainty or disagreement about

the ARTERBURN Haplogroup.  Our Big Y test results has confirmed all SNPs that

identify our branch of subclades within Haplogroup R thus far to R-Y46, and 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 in the Old World is disclosed.  Each new subclade/SNP

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 may 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.


Both an alphanumeric nomenclature (e.g., R1a1a1) with corresponding Y-SNP

numbers (e.g., R-M417) have been used concurrently to designate subclades

of Haplogroup R on the Y-DNA Tree of ISOGG.  However, SNP numbers have

proven to be more congenial to an uncluttered display, as alphanumeric

extensions can appear bewildering with the increase of so many subclades

among the 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 abroadGujarati, Sri Lankan

Tamil, Indian Telugu, and Bengali ethnic groups are representedThus, 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 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. 

TMRCA 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.

Haplotype (STR) was identified and established
by the overall match of 37 (DYS#) STR markers from the Y-DNA test
results of four documented descendants (three direct descendants of
William and one of Peter).  The difference in number values of some
markers represent "one-step mutations" (see colorized chart), and 
is termed Genetic Distance.   Most of these mutations occurred 
with markers known to change or mutate more frequently than other
markers.  As many as two (2) STR mutations (i.e., Genetic Distance
of two) within the 25-marker profile have been known to occur from
just one generation to the next, or between a father and son.  These
more volatile markers serve useful purposes for genetic genealogists,
such as an indicator of branching within family lines, and also for
calculating time or number of generations to the most recent common
ancestor (TMRCA).  Seven to eight generations separate all of our 
ARTERBURN descendants who were tested from Peter and William
and from each other, so there are no real surprises here. 
The Y-DNA test panel of Peter's descendant (67603) has been
expanded to 67 (DYS#) markers of STRs, which will improve the
accuracy of future matches for discovering our nearest genetic
relatives, whether from before or after the beginning of the era
of surnames.


Statistically and for the purposes of our project, these results are
sufficient for determining our Y-Haplotype even though further such
STR mutations might be uncovered if additional descendants were
tested, resulting in a slightly different modal Haplotype (i.e.,"mode").
