There have been five new kits ordered in 2009. One of these kits just came back with no match whatsoever to any of the kits tested so far.
Also, one of these new ones is a Cass surname. However, unfortunately, he didn't match any Case or Cass. His Cass was a modification of Cash in the distant past.
We have a results which matches older kits that, up until recently, had no match. These are from the haplogroup E1b1b1a, which is different from the other northeast Cases. To help differentiate the groups, I have put the haplogroup after the group name. Since these four men have the earliest Case ancestor in the northeast USA, I have named this group Case/Cass(haplo E1b1b1a). This group includes the surname Cass, a descendant of John Casse.
Kit # 104680 results came in for the Carolina group. Even though DYS 385a (a fast mutating allele)is off by one unit, this person is still a known match for my DNA because his grandfather and my grandfather were brothers. This just shows how there can be small mutations within the same family line.
Results for deep SNP-I tests reveal that 7 of the Northeast Cases are M253 subgroup of the main haplogroup I (P19). This sub group is I1a. These results are reflected in the Y-DNA results of our group webpage. I am also part of the I1a (M253) subgroup of the main I haplogroup (P19),which means the Carolina Cases that match my 25-35 markers will also be I1a.
We are now getting a better idea how closely the Northeast Cases and the Carolina Cases are related. In fact, my kit#27579 (SC) is a 36/37 match to kit#83870 (NY) which means that he and I have a 99.99% probability of a common Case ancestor in the past 24 generations and even a 97.51% probability of a common ancestor in the past 12 generations.
I have established what I call Northeast Cases #2 (N/E #2 Ancestors). This group has their oldest known Case male ancestor in Aylesham England and New York. However the DNA of this group is not at all common with the group entitled Northeast Cases. The plot thickens!! We need more Cases to do DNA testing.
There are now 9 kits with no close DNA relationship to any other kit. Hopefully we get some new Case males to submit DNA so we may be able to define some new Case lines.
Based on the tests done , we now know that the Cases from the Carolinas and the Cases from New York have a 99.98% chance or a 97.78% chance of having a common ancestor in the last 24 generations (depends on which Carolina Case you compare to). This appears to confirm that sometime before 1770 Cases from New York migrated south, or separate groups of Cases came to New York and the Carolinas from a common ancestor in England.
I was trying to post the relationships of each of the kits, but we are getting too many test results to make this practical (good news that we are getting such good response). If any one wants to know the exact probability of a match to another kit within a given number of generations, just send me an email and I will forward a report to you.

This is an approximation, but certainly needs to be verified by testing if you want to be certain.
Just because you are a female(x-x chromosomes) Case, don't despair. Try to find a nephew, uncle, father, brother (any direct Case male who carries the y-chromosome) who will take the "cheek swab test" to get DNA from your line. Of course, you may submit a mtDNA test, which tracks the female line.
Any questions or corrections should be submitted to the Group Administrator.
