Thorfinn 'The Black' Sigurdsson, II Jarl of Orkney - @Thorfinn 'The Black' Sigurdsson, II Jarl of Orkney

Your inlaw path from Thorfinn and you son's path are currently the same. Put the green pin on Thorfinn, and then go to both of you. Sometimes Geni has weird glitches. Of course at this distance, it is not unusual to have multiple paths. If you do not also use WikiTree, one nice function there is a dropdown which shows multiple paths.

Why do you suspect an inlaw relationship on Geni to Thorfinn would also have a DNA connection? It isn't clear from what you have written about either of your FTDNA tests. R-M269 is incredibly common in Europe, which you must know? I2a1b, I2a2, etc are also very common in the Orkneys. Thorfinn may have been an R1b, an R1a, an I..... I've never seen any mention of Y-DNA conclusively linked to Thorfinn's family. Have you? Or mTdna?

This is beyond the limits of autosomal DNA. You will probably find some cousins who have him in their tree, but I wouldn't personally use that alone as confirmation of descent. It's too far back.

Thorfinn 'The Black' Sigurdsson, II Jarl of Orkney is my 33rd great grandfather. Are you asking for a descendant to share dna data? What is your question?

I use WikiTree. I use many platforms. i am surprised WikiTree did not acknowledge DNA match with you guys who claim to be descendants. Most curious 🤔

My Wiki is a stump, so in my case that is likely why you may not see a path. I redirect people here since I have only built out a couple of lines there. Project for this winter! I do have Gedmatch kits listed though. Here is a comparison. Seems we likely have a common ancestor or two several hundred years ago as the quality is decent enough. No way to confirm who it may have been though. We do not have an X match.

If you set to 7cm, we have the following kits in common. Some have trees, so maybe some clues there? I can also map our match and see what comes up as possible overlap.

Kit 1: JT2695186 (Karrie Welborn)
Kit 2: DP713053C1 (Vanessa Hosea Brooks)
Found 57 matches that match both kit JT2695186 and kit DP713053C1

This is supposed to be a 'fun' Science. Why? Because the answers are in our DNA. Not in the handwritten journals of scribes we hold so sacred.

My DNA has been full genome sequenced. Also my son has a Big Y.

Attached to our profiles on multilpe platforms for science research.

I also provide Gedmatch kits. I DNA tested on every major platform and created a Combined Gedmatch Kit. What I do not provide is attitude.

I use Geni, WikiTree, Geneanet, just to name three but there are more Trees platforms. I find Geni very user friendly because I can actually read your collaborative interactions.

On Geni I can see the Relationship Path. I can see where my roadblocks are.

My son's path and my path are not the same. They Start and End the same but many different ancestors in between. I hope you can find your NN

I am sure her Family is inside the Path. This was not just about Thorfinn. Look outside the box. :-)

Ok, I mapped our match. Do you have any known Native American ancestry Vanessa? That seems the most likely possibility for our match, with the smaller segments being European. You also overlap with a few matches I have from the Calvert family, so you might want to research that surname, if you have not preciously. I have no way of knowing if this is by chance--we could simply be mutual cousins--or if it relates to that surname specifically, but given the timeline, it seems possible.

Vanessa, I'm not following you? You have an inlaw relationship on Geni to Thorfinn, but you believe you also descend from him? Is that what you're getting at? Unless your mTdna is the same as his, and as far as I know his mTdna is unknown, how would we prove this with DNA for any of us? You and your son would not share Y-DNA. Again, if he has the same Y Haplo as Thorfinn, that would be cool, but R-M269 is the most common one in Europe, so I feel as though I'm missing something here?

I don't think we can use our autosomal DNA to solve the questions in the other discussion about if Ingibjörg the biological mother, if that is where you're going with this post? We can possibly figure out our connections, but I think that is the limit. Autosomal DNA is not running back that far, and as far as I know, her remains have not been tested, nor have Thorfinns? Do you know differently? Do we have someone here claiming a direct, unbroken maternal line to Ingibjörg who has tested? If we do, then we might be getting somewhere with mTdna.
