Marker Mutation Analysis

(This page updated October 22, 2009)
DNA Participants, Please Note: This DNA Project Website is maintained on a voluntary basis.  If you see an error or omission in any of your information on this or any other web page, please don't hesitate to contact Patrick Childress at londonwildcat@earthlink.net and request an update!  We rely on your eyes to catch our mistakes...

When we examine the Y-DNA results, we speak in terms of "repetitions" which are the numerical values assigned to each of the 12-, 25-, 37- or 67-marker positions.  These "repetitions" range from a low of about "8" to a high of about "38" for each marker, or alleles.  Once we've managed to group individuals together in a common "Clan" based on the similarity of marker values (repetitions) on each of the alleles, the mathematical value of each marker is immaterial.  For example, we just know that Clan 1 is comprised of eight individuals whose values are identical on each of the 34 of 37 marker values (alleles).  Thus, we can effectively discard all those marker values in each Clan where all the members have identical results and concentrate only on the markers where there are mutations from the baseline for the Clan.  (The baseline is that repetition number which is associated with the greatest number of participants for each marker.)

The purpose of the following table is to draw the reader's attention to those mutations from each Clan baseline for each participant.  By carefully examining each participant's mutations, particularly where there are matching mutations with other participants, we can begin to draw fairly accurate conclusions concerning the Barron family tree and its various branches.  Any of the 12-, 25-, 37- or 67-markers not shown in the following table indicates that all participants within that Clan had identical mathematical values for that marker.

Click here for a complete spreadsheet of all marker values for all participants (wait a moment for the data to load to the page).

What do these "Clans" mean?  Every individual in each Clan is, by definition, a cousin to every other individual in their Clan.  Perhaps the relationship is "third cousin, 10 times removed," but each is a cousin to the others by virtue of having a "recent" common ancestor (say, within the last 800 years or so).  Remember, in order for an individual to be assigned to any Clan, their 25-marker DNA test results must demonstrate at least a 25% probability of having a Common Ancestor within the past 24 generations with any other individual in a Clan.  Click here to review each Clan Lineage.

(Red marker numbers below  indicate a "fast mutating" marker...average mutations occur only once every 6,000 years or so; these fast mutating markers can change more quickly.  Click on the Haplogroup designation below to go to a definition page describing that Haplogroup's origin.)

OBSERVATIONS:
The following notes pertain to the existence of individual marker mutations when compared to the baseline of the MRCA.  Mutations that exist in only one case are highlighted in yellow while those carried by more than one participant are highlighted in green.  These mutations are more important as they can lead to the identity of more recent family lines.

 13 14 12 17 17 35 The identical mutations on the 439 marker (fast mutating) indicates that Donald and Arlin possibly are more closely related than the others in this Clan.  The relationship calculator suggests that the probability of a common ancestor within the past 8 generations is about 85%.

Oran, Michael David (kit #50436) and Keith (kit #43129) are known not to have a common ancestor within the past 6 generations and they match perfectly on all 67 markers, indicating a 98% probability of a common ancestor in the last 7 generations.

While unusual, multiple step mutations can occur in a short time span, as evidenced by a +3 step mutation for Joseph Russell Barron (15314) and and Justin Smith Barron (117230) and Chip Barron's -5 step mutation on the YCAIIb marker. Joe and Justin have a close relationship to Chip (4th cousins, once removed) and all descended from William Barron, Sr.'s son, William Jr.

67 marker   		Jerry Wayne Barron 13 15 15 17 12 24 18 37 10 10 20 12

The ancestors of Jerry Wayne Barron, Richard Larry Barron and John Lee Barron migrated to Chambers/Tallapoosa Counties, AL in the 1830's.  Jerry descends from Robert Barron, Larry and John from Thomas Barron.  Robert and Thomas were brothers whose father may have been Thomas Barron of York/Union Counties, SC.  All three participants experienced a mutation from baseline on fast-mutating marker 439 - the only three participants in this clan with that mutation.  Jerry and Larry have one-step mutations, John has a two-step mutation.

Justin Smith Barron

 12 14 15 17 12 27 19 37 - - - -

Justin and Joseph Russell Barron (15314) are descendents of William Barron, Jr.'s son, Smith Barron.  The 3-step positive mutation of 27 on the YCAIIb marker has to have occurred in the Y-DNA of Smith Barron since another descendent of William Barron, Jr., Chip Barron (71454) through son James, shows a 5-step negative mutation of 19.
121466
67  marker

Michael James Barron

 12 15 15 17 11 24 19 37 10 10 20 11

Michael James and Kenneth Derald Barron share the same unique, single step mutation of marker GATAH4.  Derald likely descends from William Barron of Pendleton, SC and later Cass County, GA, a near relative (possibly a nephew) of Michael James Barron's ancestor, Alexander Barron.  Both William and Alexander settled in Pendleton County, SC in the late 1700's.

(contact is Julie Barnes Weston, daughter)

 12 15 15 17 12 24 19 37 - - - -

Daniel Barnes matches perfectly the Clan 2 baseline on 37 markers.  This is rather remarkable since the MRCA between his line and the other four participants who also match the baseline on 37 markers probably lived in the 1600's.  Family tradition indicates that the likely ancestral line of the other four matching participants (Oran Barron, Michael David Barron, Brent Cody Barron and Keith Reeves Barron) left Scotland for Ireland in the mid-1600's. Their immigrant ancestor(s) arrived in America from Ireland in the mid 1700's.  Daniel Barnes' immigrant ancestor came directly from Scotland in the late 1800's.  Somewhere between the 1600's and 1800's, Daniel's family came to be known as Barnes rather than Barron

(kit #15363) and Jack Leslie Barron lived within the last 8 generations.  Family lineage and documentation suggests that this common ancestor lived within the past six generations.  (See the Conclusion Page).

67 marker		 Charles Henson Barron 13 12 29 15 18 12 18 34 40 12 10 The fact that only Charles Henson and Jack Leslie Barron both have a mutation at the marker CDYa marker (a slow mutating marker), gives rise to the thought that they may have a common ancestor whose DNA marker mutated since the common ancestor for all these participants.  However, the fact that there are five additional mutations between these participants seemingly contradicts this possibility.  Additional research is required.
