Happy Father's Day to All !
No new results as yet. I have received a quick analysis of the results that we do have from DNA Heritage. I have posted it here:
DNA Heritage Analysis of 3 Results
It confirms my conclusion that the DE result is no way related to the " T " spellings, corrects some of my terminology, and changes the actual mis-matches to 3 instead of 4 markers.
Be sure to take a look at it.
Apparently parts of the second page of analysis that come with certificate of results from DNA Heritage is missing. DNA Heritage has sent me an updated second page that contains the missing information. It is an attached PDF document to an email. If you do have this problem and have not received an update please contact the company and/or me.

This is breaking down spectacularly so far. I am very pleased. Out of 3 results, one each from TE, TI, DE spellings we have two distinct haplotype groups.
HG1 for " T " spelling and HG2 for the DE.
Even a 12 marker test could place an individual in either of those broad groups, as only the DYS426 and DYS392 need be known.
In addition, within the HG1 Haplotype we have a 4 marker difference between the English TI line and the American TE line. This is not so many that a common Ancestor is so far away as to be useless, but far enough that a 37/43 marker test can place any individual definitively in either of those lines.
The 4 markers leave room for differences further within those two distinct lines to show up, through a 37 marker test, so that exact matches are possible within 4 generations as they promote.
Analysis
The 37 marker tests are new, and not much analysis exists on them yet. However, If we break the results down to the more common 25 marker test of Family Tree DNA, we get results that look like this:
There you will see only 2 markers do not match out of the 25, and they only differ by one. I have provided links so that you can follow FTDNA's analysis of this result. We get a common ancestor between Group A and Group B of a very optimistic 14 generations, (Samuel's great grandfather in England), or absolutely, positively, no doubt about it, - within the last 66 generations.
Another way they look at it is to say that 95% of the possible values of Time to Most Recent Common Ancestor lie between 6 generations and 82 generations.
Midpoint of that spread is 44 generations, or around 800 years if use 20 years per generation.
With only one result from each group, I do not think the additional 12 markers with the two additional mismatches helps us yet. The other two mismatches the 37 marker test adds are DYS442, and DYS461. However, we do know positively that present day descendants of Samuel of Massachussets share a common ancestor with a present day father and son in England.
We cannot say that about the DE spelling. It is still out in left field, without a match. Cannot say much of anything except comment on the different haplotype group that it belongs in. A value of 11 at DYS426 places this result in the HG2 Haplotype Group. 50% of Norway and 18% of England carry this haplotype. But in no way does this result share a common ancestor with the Group A and Group B.
Ouch.

As predicted, Relative Genetics has released their 37 marker test. Uses the same markers as the DNA Heritage $199 test. To clear up any confusion, both tests are 37 marker tests, that have 43 possible values. Link to FAQ here.
There are 19 tests left through DNA Heritage carrying the $199 price.
Current Price list at Relative Genetics:
- Individual - 24 marker (26 value) $155
- Project - 24 marker (26 value) $195
- Individual - 37 marker (43 values) $195
- Project - 37 marker (43 values) $235
