Joe, Sorry to take so long to respond. I hadn't seen Steven Fox's spreadsheet before. Couldn't find him or mention of his tool on Google. Finally, I discovered he was part of the Visual Phasing Facebook group. So I requested membership, and Blaine Bettinger, the group coordinator approved me. So finally I ...

Debbie: Well, I'm just looking at the results. And FamilyTreeDNA seems to have many fewer disprovals of IBD by parents at any given cM level than AncestryDNA does.

Very interesting, Debbie. So then it seems that FTDNA's criteria of at least one 9 cM segment is better (i.e. produces fewer false matches) than AncestryDNA's combination of phasing and inclusion of segments down to 6 cM. That may be indicative that AncestryDNA's phasing combined with its Timber may not be ...

Joe: I'm hoping to come up with a method of chromosome mapping using the match information and then display the map in the DMT output. If that is successful, then it will be an automated system that does what visual phasing does plus more (sometimes going back to generations further than grandparents). I think ...

Debbie: I agree with everything you say (except maybe one thing, which I'll likely write about in a future blog post). I was specifically talking about triangulation. Yes of course, a match between two people can be IBD. But the point of the article was to dispense with the notion that triangulation means ...

Thednageek (Leah): Excellent questions, and thank you for them because you're making me really think. I'm hoping to use triangulations to incrementally build up a chromosome map of ancestors the way Jim Bartlett has done and describes on his segmentology.org blog. It is still a work in progress. From a ...

thednageek: I think Ann beat you by a couple of minutes regarding 23andMe, so I had to give her credit for that update. Re your 3rd possibility: Whether a segment is from a recent common ancestor or a distant common ancestor, it's still the same segment from the same ancestor that all the people in the ...

We'll likely get to meet again Tony, somewhere, sometime. I don't go to RootsTech each year. I previously was there in 2012 and 2014. I usually need a good reason to go, and not being there for 3 years was my good reason.

Thanks, Jill. My motivational goal is really wanting the program to be able to figure out how some of these 7,000 DNA-relatives of mine are actually related to me. I think ultimately, I can get the program to do it. Slowly getting there. Louis
