Hello everyone- I can desperately use some help. 1. Where should someone match on the ISOGG chart if they share 40.3 on X and 92.5 auto? 2. Is there a list similar to the ISOGG relationship-DNA cM chart, but that includes half siblings higher up? Does it matter past 3 gens up? Is there any way to estimate, or is it just too far off exponentially? The scenario: I have three matches. Underlined are the matches to the DNA donor who does not know paternity. (Maternal side known & excluded). GH has 15 kids, 12 with MJ, 3 with MB. Endogamy is happening amongst these lines. DNA submitter b 1965 same era as WD and MJ. TB born 1924. How does one get that much X, but so little cM? MJ wife 1----------GH------------MB wife 2 EH CH FH HC GJ TB* VF GJ 92.5 & X 40.3 WD* MJ* 57.6 44.6 TB matches 92.5cM (35.6 largest segment) Also 40.3 X match. WD matches 57.6 cM (28.5) no X MJ matches 44.6 cM (22.9) no X WD matches TB 64cM (26.3) MJ matches TB 75.7 (32.5) WD and MJ do NOT match each other I would be grateful for any insight. I have looked at these folks too long and aside from documenting descendancy from everyone, I have no other tactic for exclusion or directing my focus, and I feel I am missing something significant in these numbers. Many of these descendants had 10+ kids. I am beyond overwhelmed. GH, MJ, and MB were are immigrant pioneers, with many parents and siblings coming to the same area. Results/matches from gedmatch, 23andme, and familytreedna. Ancestry still processing. I also have two other matches with a different MRCA pair that lives about 30 miles away in the pioneer time frame. Unfortunately some families had 20+ kids. DNA donor kit F427838. Thank you in advance to anyone reviewing or responding. I am certainly appreciative of any help and ideas. I am feeling pretty dumb right now. Regards, Patti Easton

Dear Patti, I agree with Kathy Johnston's comments. The way I approach situations where there are matching segments on the X chromosome as well as matching autosomal segments is to first put aside the matching segments on the X chromosome and focus first on the total number of shared cMs. In this particular case, two people who share 92.5 cMs are likely to be no more distantly related than 1st cousins once removed. If there were no endogamy involved then we would expect the most likely relationship to be 3rd cousins. Since endogamy is involved a relationship as distant as 4th or 5th cousins is possible. If you are using Family Finder matching HIR data then I would suggest you delete all HIRs under 5 cMs before you start trying to predict the genealogical relationship. Blaine Bettinger's chart at http://www.thegeneticgenealogist.com/2015/05/29/visualizing-data-from-the-sh ared-cm-project may also be of help to you. I use the X chromosome data to help determine which ancestral lines the genealogical relationship may have been on. When you are in doubt about the genealogical relationship, testing more relatives from various lines of descent can help you better estimate the most likely genealogical relationship. I average the results for the people at each generational level, as I did in this project: http://blog.23andme.com/ancestry/who-were-the-parents-of-jacob-youngman.

Hi Tim, Thank you for the links and responding. I think you are exactly correct, I am overwhelmed by the data. Deal with one, then deal with the other. The chart you sent is the one I use, however what is throwing me is the matches descend from GH and two different wives, and TB is farther upstream than I am used to. Also many of these families have 15+ children. I am hoping to use the X to eliminate lines and possibly place me closer to the candidate lines. I will start from scratch one thing at a time. It is also scaring me a bit that endogamy is skewing the numbers, and that even after reducing the field there are so many descendant lines. But you are correct, take the cM, then take the X and create the pathway. Thank you very much for the reply!
