DNA Painter Library of Matches: A Powerful Tool to Decode Relationships

[@glenjones6980]

In the real world many of us only have our own test and for whatever reason have no option for testing parents/grandparents/siblings, we don't have the option to pick and choose a suitable test. Whilst I watch the channel to become aware of some of the tools out there I invariably struggle to see how I can use many of them in my circumstances as the examples shown use test results I can only ever dream of. For once it would be nice to see something that caters for those of us who have to deal with unknown inactive matches, generally without trees that are at best 400cM and often half that amount.

It sounds like you and my wife are in the same boat - the Debbie Downers of DNA. She has been able to test a handful of people (two of which are not her parents as they died before testing was available). In that case, just focus on the basic tools: Leeds Charts DNA triangulation with Chromosome Browsers Then leverage advanced genealogy research such as Surname Studies, Locality Research of Specific Groups, FAN Club research, and descendancy research. Those are the tools Devon keeps going back to since very few of the tools I share can assist her small family problem. (More on that here: kzbin.info/www/bejne/pnunm3udZpiEnas)

@@FamilyHistoryFanatics I can see my comments on numerous uploads have been a waste of my time (though clearly not yours).Thanks for the compliment by the way. I could return one in kind but I was brought up a little better than that.

Wouldn't a paternal grandparent and maternal grandparent autosomal chromosome patterns look similar to each other? Why differentiate in the side of the family at the gross level of determining relationship?

[@junebutka6571]

I don't have parents or grandparent's DNA to share. I would not likely to use this at this stage of my learning. Maybe later. Did she want you to show examples, to explain it?

[@FamilyHistoryFanatics]

Yes. Devon recommended that I not only say... here's the tool. But she recommended I show some examples and walk through the analysis process. Did that help?

There seems to be a lot of guess work using this tool. “Looks like this”. “Looks like that”. Might be useful for fairly close relationships but I was of the understanding that DNA inheritance was completely random? Seems like a lot of guess work for little reward. I’ll give it a miss.

[@FamilyHistoryFanatics]

How wise you are my friend. The tool is guess work. It's designed not to give you definitive answers but to help you narrow the scope of your research so you don't spin your wheels. You start with a more targeted research question and then expand out if the first hypothesis doesn't work. We all have to start somewhere with our DNA matches and this tool is one that can help us make better educated guesses as where to start.

Great addition to DNA painter! Hope you are having a fantastic time in Europe.

[@FamilyHistoryFanatics]

We had a blast. Thanks for watching while we were gone.

I’m going to try this with an unknown match with my Aunt who may be a 2C1R. He has a tree with only a maternal surname and he does not respond to emails. It looks like he may have been an adoptee or has unknown paternity and that is where the match is on my Aunt’s mother’s side. Of course, that is the still developing bio line for her mother who was adopted.

[@FamilyHistoryFanatics]

Ohh! That's a great one to investigate. Good luck.

It would be also useful to know which segments resist breaking down. I think, for example, the X chromosome is like that. At MH, I match >100 people on the "infamous" (so I've been told again and again) ch. 15, on the far left. The range is about 8 cm to 45 cM, depending on the match. In most cases, with JUST that one segment. I've never been able to do anything with those matches. (Any match >30 cM is a big deal for me... usually.) People at various FB group tell me that it must be a very distant ancestor... pointless to pursue almost. I suspect everyone had a distant Jewish ancestor. That's all I get out of it. Longer stretches on some of these "suspect" chromosomes might mislead one... as they try to guess at the possible relationship?? (I think I'm going to go back and analyze this again... looking for a second segment and looking at other sites.) BTW, if almost all of one's DNA comes from an endogamous population... I think they might also have to be wary... with this library of chromosome paintings.

Andy, my uncle has a match of 3-4th cousin to whom i believe my 4th great grandpa william blalock's brother of the match's 3rd grear grandpa jeremiah blalock who our william and jeremiah share david harrison blalock and first wife mmary anne beale i am thoroughly convinced. WHAT IS YOUR THOUGHT ON THIS? tHANKS andy

[@vucat]

This is a great addition, but I wish they would make it so that you could have access to your chromosome map and add that to make comparisons. You are having to move back and forth, but having the ability to visualize them against each other would really help. I love how you are breaking down patterns to connect the different maps. Thanks for the video.

[@FamilyHistoryFanatics]

That would be a cool feature rather than going back and forth.
