Reply to comment by grandj in [OC] Endogamy of Ashkenazi Jews visualized through DNA matches by ItsDaBunnyYT

This is with Force Atlas 2, but rounded out in preview mode. I've tried a couple algorithms, but it's just so incomprehensible. My mother has a total of 215,525 matches on AncestryDNA, and her DNA is so fuddled that she is practically related to everyone on both sides. My point in visualizing it (this is the highest 1,000 matches she has), is just to visualize the difficulty with this. Her Collin-Leeds is just as bad. I've tried playing with parameters and modularity, but it seems to be quite stuck.

Ok then maybe you should set a limit in the strength of the relations you want to display, and remove the edges that are under it. You would then have a graph of the closest relations and it would be less dense, like a "backbone" of your graph.

DNA tests are a scam. Do documentary genealogy if you want to know anything valid.

That’s easy for you to say. All the records of my town was destroyed in the Pogroms.

That's your first mistake, perhaps. Underestimating the complexity. Already at the level of just great-great grandparents, most people come from as many as 8 villages (fewer if there was tremendous inbreeding, like in your case [sorry, is what it is]). Perhaps each and every one was destroyed, and all of their parents' village records in as many as 16 more villages, were ALL destroyed, too; or you're so inbred there were far fewer villages containing records about y'all. Doubtful, though, that you are that inbred. Whatever you find document-wise will be immensely more illuminating than the DNA tests, no matter how scant.

edit: perhaps supplement your research with what use you can make of others' research on FamilySearch.org . That website helps folks compare notes on family trees. Some people log in to find out most of their tree has already been fleshed out by others who share many of the same branches.
