    Hi Jill – thank you for sharing.

    I am not sure that, despite your evidence that the pedigrees show no evidence of collapse, you have explained clearly the tree completeness for both yourself and your match. I appreciate it is unlikely that there is another explanation given each of the relationships on the lineage being discussed had been verified and you had also looked at spouses on your match’s lineage. But it would I think be useful to say something like that to the level of great great grandparents you have identified 100% of your ancestors and similarly for your match’s tree 100% of the 16 great great grandparents have been identified as well as intervening generations.

    I think a single match with no chromosome browser and no triangulation could really be regarded as evidence, rather it is an indication of a likely connection.

    I don’t think you have enough evidence of a genetic relationship as the tools at AncestryDNA don’t give you the means to demonstrate such a relationship and because you have matched with only one descendant of Jan Middents Cornelius Bode and Antje Eckhoff .

    I have had a go at triangulation https://ayfamilyhistory.com/2019/06/15/triangulating-matildas-dna/ but I notice I have not dealt with the issue tree completeness for my matches!

    I have found your write up most interesting to think about how we ca use DNA to help confirm pedigrees.

    and best wishes for a continuing recovery!

      Thanks for your thoughtful comments!

      I am not sure the length one should go to proving no pedigree collapse and I am not sure I agree with you. There certainly is an on-going discussion about when is “enough” on the issue of tree completeness, particularly of the other person’s tree. Some people think you ought to exhibit reasonably exhaustive research of the other person’s line to the level you are proposing before you can say you have eliminated the chances of pedigree collapse. Other DNA experts have disagreed and suggest that two generations back on the test taker’s line is OK, because the DNA that would pass down would probably not influence the total significantly. I think that the fact the Bodes were only in MI for 5 years; each family came from different countries, and almost everyone’s parents were immigrants is still probably enough for the portfolio. One certainly could expand on the investigation of the family, if one thought it necessary….but that might be a whole other KDP!

      I am only verifying a lineage—not doing a proof for an unknown father or mother, or grandfather etc. You can see what lengths were taken in my article in the December 2018 NGSQ article about identifying a father for Molly Morelli (in the resource list). I would like Ancestry to provide more tools (segments etc.) but they don’t. I probably should have looked at FTDNA or My Heritage to see if I had links to JMCB there, but I also wanted this to be a teaching article for those that are not so DNA adept. (And, I am no expert!)

      FYI: I did put the “100% complete Bode tree to two additional generations” comment in #20 footnote. I had it in the body of the document for a while. That’s a good suggestion to daylight the complete-ness of the Bode tree more by pulling it into the body of the doc.

      Thank you for your comments. When is enough enough will probably be an evolving debate and may vary judge by judge.


  2. Hi Jill! It’s great to hear your good news. I am so glad your health is improving and you are feeling stronger. I think of you often!

    Hi Jill,
    Thank you for posting this–I look forward to reading it. I’m sure there will be much to stimulate my thinking, as with all your work.
    I’m sorry to hear of your health challenges and thankful you’re doing so much better.
    All good wishes–

    Jill, Good to hear from you, and glad you are rebounding from you health issues. Just a personal note – I was diagnosed with leukemia (AML) in November of 2018. I am feeling much better now, and am also in remission. Have done tests for DNA in case I have to have a bone marrow transplant at some point. So….I know where you are coming from, and hope the future holds only the best for you.

      Jan, good to hear from you as well. Sorry about the diagnosis but it is amazing what medical science has done with our diseases! My chemo protocol was released by the FDA just 2 weeks before my diagnosis, saving me $$ and time (didn’t have to get approved to go into the clinical trial). {{hugs}}. Jill

    Jill, this is a very welcome post! I look forward to diving into your sample when I have more time. You’ve definitely given us food for thought!

  6. Thank you for sharing this, Jill! I am looking forward to re-reading this piece of your portfolio and then reading this update. Thank you for your dedication to education in the genealogy community, I am very appreciative of the time you sacrifice.

    Reading about your decisions and rationale was good for me. It is as though you are writing your project for a moving target! Keep moving forward!
