NOTE - Ftdna's comment about marker DYS464...for those of us in our group; this is the number one mismatch between us at the 25 marker level and it's at DYS464c which they say "moves most rapidly" (rapid mutator which can occur between father and son or grandfather to grandson etc.). So this means that those of us who are in our group that all share this I1 (Norse) and or I1d as I believe more of us would show if they would have their SNP's tested too, is saying that we MOODY's who match at 24/25 with only the one marker off at 464c, are more closely related than we thought.
Having said all of that...this means that theoretically, according to FTDNA, we should be able to Find our Common Ancestor "within a genealogical time frame" that they speak of. So, our earliest proven ancestor Thomas MOODY b.c1710 in/of Aghadowey, Co. L'derry, Nor. Ireland who married first to Jean McCuiston/McQuiston and 2nd to Mary WITTY, his ancestral lineage line should be able to be found IF the documentation or any wills or records are out there to prove his line to us Genealogically. I'm sure many have searched the records for his ancestry, I know I have and so far haven't been able to obtain anything definitive. There's lots of speculative evidence which very well could be part of his line, but a document or will of some proof would really be great.
Here is a list of the MOODY's of our Ydna group whose earliest ancestors, again, according to FTDNA's comments here under the meaning of the 25 marker Ydna test results as far as Common Ancestors go, should all theoretically share a common ancestor...I have tried to list these men from earliest to latest birth date wise where possible and known. Again, all of us who fall under the ancestors of these lines with the exception of #8 below, are only off by ONE marker at DYS464c a very rapidly mutating marker, at the 25 marker level and our Common Ancestors should be able to be found in a genealogical/findable time frame. And we ALL share the same HaploType (I1a-N or I1d as some of us have found we are now via SNP deep clade testing which is still of a solid Scandinavian-Celtic line).
1-Thomas MOODY b.c1710 Aghadowey, No.Ireland who m. Jean McCuiston/McQuiston and 2nd to Mary WITTY
2-James MOODY b.c1745 (my 5th grt. grandfather...either from Nor. Ireland or Scotland) who m. Elizabeth DONALD (Donnell) who was b. 1750 in York Co., Maine
3-Alexander MOODY b.c1747 of Lenamore/Magilligan, Nor. Ireland who m. Priscilla DICK
4-James MOODY b.c1759 in/of New Jersey who m. Sarah BAKER in 1784 and they removed to Annapolis Co., Nova Scotia, Canada (my exact ydna matching MOODY cousin at 25 markers which, again, according to FTDNA; means we share a very close common ancestor somewhere that we should be able to find)
5-Samuel MOODY b.c1786 a weaver from Nor. Ireland who m. "Martha" and landed in Baltimore, MD but removed to PA.
6-James MOODY b.c1808, weaver of Balnamore, Co. Antrim, Nor. Ireland. (this James is off by 2 markers to me and I believe the rest of our group as well, which according to FTDNA means we are still very much related but that our Common Ancestor is further back in time, but still within a "findable" genealogical time frame)
7-John P. MOODY b.c1816 boot/shoe/hat maker of Nor. Ireland who was m. to "Jane"____ and who came to Kings Co., NY with family but who later removed to Yonkers, NY and then to Fairfield Co., CT where they continued in the hat making/haberdashery business from census info.
8-John MOODY b.c1750 who may have come in from Nor. Ireland or Scotland and resided in the Darlington Co., SC area. This particular John MOODY is of our same HaploType but is our furthest or least matching Ydna Moody cousin to date. He is off by several mismatches to the rest of our group and FTDNA states that unless we can find the common ancestor between us Genealogically, that this MOODY is just a coincidental match to us and that the common ancestor is too far out in time to be found, in other words, our common ancestor dates back to before a time when records and surnames were common. Again this does not mean he is not part of our very ancient Moody family, his matching Ydna and HaploType shows that, its just that John is the furthest away matching cousin we have at this time.
So aside from ~possibly~ #8 above, we should be able to find our Common Ancestors that link the rest of us together. If we could just get back One More Generation on any of the above MOODY's it might be that they are the person that would finally open up a great deal more information for us to research regarding our Moody branches.
Hope this is helpful and that I am understanding this report from FTDNA correctly according to their charts.
