How to document when au appears to confirm paternal grandfather was adopted and is not a biological relation?

On paper, I have a third cousin once removed here on WikiTree who in on Gedmatch.genesis, as am I.  Comparing our DNA shows no matching whatsoever.

My DNA appears to strongly indicate, when combined with the genealogy I have compiled, that [Batcheler-21], my biological paternal grandfather, was not the child of [Batcheler-22] and [Totten-284].

Should I wait to see if any further Totten family members are tested (there are very few Batchelers out there)?  My birth father hasn't been in my life for 50 years, but is stll alive and is in contact with my one full sister.  I have the sense that if I could get him to test, it would seal my assumption that his bio father was adopted.

My primary question, then, would be how to accurately show documentation (when proven) that Batcheler-21 is not the biological child of the aforementioned parents (most importantly, so WikiTree and other systems don't continually try to link me to their family trees).  I'm also on Ancestry (DNA test taken there) and on MyHeritage (DNA uploaded there) as well as on FTDNA - where this all started.

I have an adoption angel working with me, but she's on temporary hiatus due to a death in the family (will likely be back sometime next month).  My big goal, and the one she is helping me with) is to find out who my bio paternal grandfather's parents really were, as that's where the central Mexican/indigenous DNA I have appears to have originated.

Many thanks!

Melissa

postscript:  I was born with XY dna and have taken FTDNA's Y-25. Next month, when they have their father's day sale, I plan to upgrade to the Y-111 as that may provide more more detail on the mystery great grandparents.

Hi Melissa,

We can't see George's family tree due to the privacy setting on his profile.
Fixed!  Thank you for letting me know!

Hi Melissa,

Do you have close matches at the Y-25 level? Just want to make sure that you understand that the Y-111 can only provide more detail if you have close matches at lower levels.

You can mark a relationship here as non-biological, which will prevent incorrect DNA test info propagation through that relationship. But for deceased individuals on WikiTree, since an individual can only have 1 set of parents here, and in order for their descendants to be able to have DNA propagation to their biological ancestors, it's recommended to use biological relationships for parentage, when known.

 

The Adopted Child Template can be appropriate in many cases to show both the biological and non-biological relationships in the bio of a profile.

Thank you for your explanation the Y testing, Rick.  At the Y-25 level I have one match at 0 genetic distance, but he does not show up on my autosomal match list. I looked at the others (2 steps), too.  There are no close matches whatsoever.

What I find interesting is other folks have stated that at the Y-25 level, the matches are more 'noise' and a higher level test is warranted.  Is this just a way to have me spend more $?

Also thank you for the link to the adopted child template.  I will come back to that and likely use it once George's true parentage has been figured out.

It's well within probability that you and a third cousin one removed by blood would have zero DNA in common, if you've both taken an autosomal test. Your dad is that person's second cousin twice removed, so it's also within probability that he will also show a zero autosomal match to that person even if you are related by blood.

To be more sure of the adoption or non-parental event, you'd need to have a zero autosomal match with a great-aunt/uncle, one of your dad's cousins, or one of your second cousins. Have you seen the match charts (and probability tool) at https://dnapainter.com/tools/sharedcmv4?

Obviously a Y-DNA test will give you a much higher level of certainty if you can find someone who should share your grandfather's Y chromosome, but doesn't.
