    I do have a tree that is available to matches. That information isn't going to be relevant to your project as they are not colonial and were not in the US prior to 1800.

    You have to have a theory that fits the data, not make the data fit the theory.

        Believe me, the theory came from the data. My imagination is not that great. What I am presenting here is just the tip of the iceberg.

        OK, here we go.

        First, I have a few points to make.

        We did have some migration out of the American Colonies during and after the Revolution as some Loyalist decide to
        go back "home" or go elsewhere. I have found cases of people living in the UK who have a line that goes back to American Colonial times. I have even seen some cases where a descendant later moved back to the USA.

        Something else to remember is that for various reasons people have been known to lie about their family history. I have learned over the past few years that DNA trumps oral history and even paper documentation.

        We are looking at connections which are far back enough that the 7.0 cM minimum segment size threshold is not a good approach. If you look at a 'one to many' list for someone and go to kits that have a 7.0 generations to MRCA, you will find many matching kits that just have one matching segment and it is not too much over 7.0 cM. We know that at one time a parent-child relationship in the ancestry had about 3400 cM of matching segments. Surely we should have more matching segments than one or a few that which we can use. Since I can find a kit that gives a (0.0, 0.0) comparison with me using 250 SNP's and 1 cM, we know that the parameters which I am using for that comparison are incapable of creating any noticeable amount of pseudo-segments. If you take the 7 generations to MRCA example and repeated the 'one to one' comparison using <250,1.0>, you will end up with a total of matching segments 1.0 cM or more amounting to something in the neighborhood of 400 cM. Some people think that each individual segment has to stand the test of whether it can randomly match with that of another kit with any kind significance to say that it is valid. That is wrong. When you already know from the big segment match that the kits are undoubtedly related, the question is if the smaller matching segments are remnants of the 3400 cM match that we knew once existed. We are getting into conditional probablities here, where what is known changes the probabilities. A simple example would be if you were part of a group which had a life expectancy of 76 years. When you are 75 years old, you life expectancy is much more than 76 years. If Family Finder deems something a match, the 1.0 cm segments are good, too.

        This minimum segment size approach to estimating relations starts breaking down once you get past five generations or so. I can have a match with a total of matching segments amounting to 450 cM but with no 7.0 cM segment which is more related than a comparison showing 400.0 cM total with a 7.0 largest segment size. If matching segments total around 400 cM of more, with or without a big segment, at least one and probably more connections are virtually certain.

        Let's get to the comparisons starting with 'one to one' @<250, 1.0>:

        F364959 (*Duffy) with F239841 (me) - (429.6, 4.1)

        F372234 (*Kern) with me - (450.7, 4.5)

        Kern with Duffy - (443.0, 4.8)

        Next we try the X 'one to one' @<150, 1.0>:

        Duffy with F367106 (my mother) - (79.1, 12.6)

        Kern with my mother - (76.3, 5.8)

        Kern with Duffy - (69.6, 6.1)

        I also have a couple of kits that I use for additional reference for this situation, but I have not asked the owners for permission to publish the kit numbers. Both belong to females who have African heritage and known ties to slavery in this part of North Carolina. I'll call them 'Lady A' and 'Lady B'.

        Lady A with Duffy - (18.4, 3.1)

        Lady A with Kern - (42.2, 16.6)

        Lady A with my mother - (16.6, 5.2)

        Lady B with Duffy - (61.1, 4.9)

        Lady B with Kern - (75.6, 9.3)

        Lady B with my mother - (83.4, 5.8)

        Lady A with Lady B - (12.9, 3.6)

        That cluster of X-DNA matches pretty well seals the deal.

        Perhaps is time for you to do a major rethink about your tree. The X-DNA matches between your grandmothers maybe eight generations back seem to support the analysis by Felix's gadget that you questioned in your blog:

        https://iowadnaproject.wordpress.com...mall-segments/

        Actually the whole genetic genealogy field looks like it could use a major rethink, and maybe a few historians specializing in early North Carolina history need to be called in, too.

          The way I approach my tree is fluid and is always looked at as new data and matches appear. My paper genealogy and my DNA matches point to the same conclusions. I haven't seen anything yet presented to cause the need for a major rethink of my tree. We have 4 generations of both side of the family tested so I have a fairly good handle on recombination and IBS.

          The matching segment sizes you are using prove we are human. I'm not prepared to work with segments beneath 7 cM let alone 250 SNP's and 1 cM. I've worked with Felix's tools enough to know we all share those segments to varying degrees.

          Good luck in your quest, but we are going to have to disagree on this one. You could find the same figures for most Europeans but that doesn't equate to mass mysterious NPE resulting from back migration from the Americas for both of my grandmothers, Mmaddi's faily and the rest of Europe.

            Imo, just because a match isn't 7cm largest block 700snps, doesn't mean you are not related to that person. It simply means theyre not within the 7th cousins range. If you were to take that match and find they are 4-5 largest block with a shared amount of 400-500cm, I'd think that would be a good indication of being related. That's a lot of DNA. They're just not within 7 cousins.

              OK, I have one for you. I was looking over your Duffy's 'one to many' list and saw a name I had seen before, Jean Mauck. Using default parameters on 'one to one' Of <700, 7.0> you have a largest matching segment of 8.3 cM, total of matching segments larger than 7.0 cM of 8.3 cM, and an estimate of 7.1 generations to MRCA. Jean is a cousin of a person that I have been working with from Maine whose aunt has a link back to the North Carolina situation that I have been talking about. My match with Jean @<250, 1.0> is (417.6, 4.3) and the X-DNA match between my mother and Jean @<150, 1.0> is (68.4, 9.0). Interestingly the aunt's X-DNA line back to North Carolina is different from Jean's, so we are finding the start of a community of people in Maine that have this particular heritage in 18th Century North Carolina.

              If you change the parameters on your 'one to one' match with Jean to my typical <250, 1.0>, the results are (429.2, 8.3). That illustrates a point that I made earlier about the total matching DNA being similar, in spite of how the largest segment happened to split. You and I are about equally related to Jean, even though you got the larger matching segment which put you on the match list.

                I could not get into Gedmatch today but do have a FF match with John Stephen Wyatt - remote cousin - 6 151067321 160602644 14.6 3053.
                Is this you?

                This John Wyatt is part of a triangulation group with 3 other people and another with an overlapping segment.

                My ancestor was probably Ann Wyatt 1704 who m. Robert Stubblefield 1702. They were born in Gloucester, VA then lived in Culpeper, VA then in Guilford, NC. Some of the Stubblefield men were slave traders.

                  No, it is not me. We have participated in this GEDmatch thread concerning the same connection:

                  GEDmatch Forums > Genealogy --> Surname Groups
                  Subject: Haute Wyatt Famil

                  I need to give an answer on that thread, but as here, I am in a dilemma. The Wyatt-Stubblefield genealogy given is not consistent with what our match is showing. The DNA segment that you showed for chromosome #6 may offer a way out of the dilemma. We match on part of that segment (6 151369602 152191128 2.1 307). A strong match of mine matches with you on three segments in the range you gave.

                  In the GEDmatch Forum thread, you gave me you brother's and second cousin's kit as well as your own. If you can PM me the kit number for John Stephen Wyatt and anyone else that is part of the triangulation, I'll try to give you a more definitive answer.

                      Thanks Marion. While I'm waiting on the spreadsheet and I went ahead and took a look a those other kits. Everyone of those kits has at least one line back to the human trafficking ring that this thread was all about.

                      For the 'one to one' with F239841(me) @<250, 1.0>, the results are:

                      F231811 - 435.6, 5.3

                      F195686 - 425.5, 4.5

                      F91757 - 486.2, 5.5

                      F328982 - 434.0, 5.8

                      A678344 - 407.2, 5.8

                      FN30278 - 474.7, 7.4

                      A515622 - 448.7, 4.8

                      All included matching segments that have meaning for the NC situation. Under default parameters of <700, 7.0>, FN30278 also matches (7.4, 7.4) with an estimated 7.5 generations to MRCA.

                      We also have X-DNA matches @<150, 1.0> for all of them with F367106(my mother):

                      F231811 - 9.6, 4.2

                      F195686 - 66.7, 4.0

                      F91757 - 6.4, 3.3

                      F328982 - 8.5, 2.4

                      A678344 - 8.8, 2.4

                      FN30278 - 8.2, 2.5

                      A515622 - 4.5, 4.5

                      I'd say that a lot of men on the way to settled Tennessee and Kentucky bought a bride on the way in NC.

                      To figure out other relations, we need to be able to identify the matching segments related to the common ancestry in this NC human trafficking ring so that we can eliminate them from the analysis.

                          Most of my families were colonial. I have a few brick walls though. I am English, Scottish, Irish, Danish, Swedish, Swiss, German, French and a smear of Native American on paper. I think one of my ancestors in Nova Scotia had an English Mail Order Bride back in the day.

                          I did not have to bump ours down that far to see a match, but here it is with your specs:

                            Fly in the ointment.

                            The problem with this theory is that all HUMANS are related. In particular, all humans descended from the ancestors that left Africa (vs. the ones who stayed) share at least 2% ancient Neanderthal DNA which continues to float around and recombine. So yes, naturally if you set the segment small enough you will find you're related to nearly everyone... everywhere. Not just in America.

                            At the same time, it can be useful if you're looking at unique segments, such as small chunks of Native American DNA which come from a population that were highly isolated from the rest of the planet for thousands of years. Even then, there are genetic influences from Siberia and the Caucuses that can cause overlap and noise.

                            'Aint nobody got time for that!

                              I always like it when someone comes along that obviously has not paid attention to what has already been said in a thread.

                              I am talking about specific ancestry approximately 7-10 generations back. I have a good idea about who the male breeders were and am closing in on the females. We will never know the names of all of the females, but we should be able to get a handle on how they are related and where some of them came from.

                              Growing up in the South, I was always curious about the number of people who claimed to have Cherokee ancestry. However a lot of them probably came from this situation in North Carolina and the Native American affiliation would be Tuscarora and other tribes indigenous to that region in North Carolina and Virginia circa 1700.

I think one of my ancestors in Nova Scotia had an English Mail Order Bride back in the day.

                                I did not have to bump ours down that far to see a match, but here it is with your specs:

                                Comparing Kit F381439 (*MCarrasco) and F239841 (*Jack Wyatt)

                                Minimum threshold size to be included in total = 250 SNPs
                                Mismatch-bunching Limit = 125 SNPs
                                Minimum segment cM to be included in total = 1.0 cM

                                Largest segment = 5.6 cM
                                Total of segments > 1 cM = 460.1 cM
                                Thank you very much for comparing. You also match X-DNA @<150, 1.0> with my mother (F367106) in the amount of (74.7, 6.2). The regular autosomal 'one to one' between you and her is (426.2, 4.2). Of course that is reflected in the results between you and me, but my father's side has several connections in that result, too. My mother is believed to have only that one link back from Canada. Taking into account matching segments that I have previously identified as being meaningful, I have little doubt that you have at least one connection and probably more to this NC situation.

                                If you are interested in trying to identify your specific connection(s), please send me a private message and I'll work on it with you.
