6/20/2014   Timothy Ragin of Anne Arundel Co., MD and Group 1

I'd like to touch on the results specific to known descendants of the Timothy referenced above.    These descendants all appear to share mutations from the "big picture" Group 1 modal haplotype (baseline) on four markers/marker pairs.    These mutations are as follows:

DYS389 ii -  29 -> 30
DYS456   -  16 -> 15
DYS607   -  15 -> 14
CDY        -  34/35/36-38  -> 37-38

I'd like to make a few points about the results table at this point so everyone understands what they are seeing.

As administrator, I have created the sub-groupings you see and have assigned tested members to them.   This took several passes and several adjustments as I was getting a feel for the family lines and individual results.   These groupings are always objective, and in some cases very difficult to do precisely.   They are not strictly based on Y-DNA Matches that you see from your account...they take into account the bigger picture.   What's important in determining family groups is not how much genetic distance there is between two individuals, but rather how much genetic distance each individual has from the deduced modal haplotype (DNA marker baseline) for the family.

Unfortunately, I have no control over how project member's results are displayed row-wise within a grouping.   FTDNA automatically displays the results in numerically increasing order.   For example, I would like the two Teague Riggin descendants in Group 1 to be displayed together, but because the one descendant has mutations at the fourth marker pair, he is put at the bottom of the list numerically since his 12 is greater than the 11 that everyone else has.  

You'll notice a lot of different Haplogroup indicators for people in the same groupings.   These differences are just a result of the level of "SNP" testing done to refine the haplogroup.

I'm continuing to adjust the results table and family groupings.   We currently have three genetically identifiable Reagan lines, and numerous men who either 1) absolutely don't match any of the lines or 2) at their tested marker level, assignment can't be made.  

Please if you haven't set your Most Distant Ancestor, do so.  It's imperative to the project.

5/12/2014  Y-DNA RESULTs

I am attempting to establish inferred modal haplotypes (baselines) for existing Regan lines.   I then compare all project members to the baseline rather than each other to determine who belongs where.  To do this, I am utilizing an Excel spreadsheet to make comparisons.  

A primary Reagan line is emerging in Haplogroup R1b, however, assigning membership to this grouping is tricky.   What's important to remember is that it's not necessarily who you match in your matches list that determines your grouping, but how well you match the haplotype (i.e. baseline) of a family line.    Most men will have incurred mutations from the ancestral haplotypes dating back several hundred years, so differences are to be expected, especially with very, very old family lines.   

I STRONGLY recommend people who want to insure inclusion in this primary Reagan line to test to 67 markers.   Haplogroup R1b is the most common haplogroup in Western Europe, and the Reagan haplotype has common markers within that group.  In some cases, 37 markers has not been enough assign people to this group even though I suspect they belong there.    I'd like to thank everyone who has tested to 67 markers already, and especially those who have gone even higher to 111.  

Within the primary R1b haplogroup, I can also see signs of a branch forming with mutations specific to that branch. It will become more clear once everyone (hopefully) assigns or updates their Most Distant Ancestor information, but it appears the Timothy Ragin Maryland branch may have readily identifiable mutations.     The marker mutations on this branch can most clearly be seen on the "colorized" results table you can access from the Y-DNA Results tab for the project.
