As I've continued to build out profiles for my ancestors and compared DNA testing results with my cousins, I've stumbled upon some things that I find interesting and/or unusual.
I feel like there should be another way to graph or display a tree that shows additional details which show endogamy patterns of intermarriage between certain families or in geographic areas over time, I'm just not sure how to add the meta data needed to do a specialized tree or graph that shows the intermarriage/location contexts in a way that is more intuitive.
I realize that others may not find this additional information useful or interesting, so I don't wish to make the profile too confusing or distracting.
Here are a couple of more concrete examples of what I am talking about if that helps to explain it better:
1. My Paternal great-grandmother's parents https://www.wikitree.com/wiki/Manning-5632 and https://www.wikitree.com/wiki/Bass-4398 were apparently 1st cousins, which leads to some genes from shared common ancestors being passed on more readily / frequently to descendants. Obviously I can mention this in their profiles, but you would to read the text of the profile to realize that this occurred.
2. I have some 1st cousins who I share a great deal of matching DNA with, and others who I share very little with, sometimes on the very edge of predicted matching DNA as shown in on: https://dnapainter.com/tools/sharedcmv4
Those that I match with the most, often prove to be related to me through both of their parents, having a common ancestor, or both their parents sharing a common ancestor for my Mother and Father.
Is there any way to mention or graph relationships which points out the closeness of matching DNA segments between individuals as well as the relationship name/degree?
Please point me to anything you know of that would help me to explore my data with the additional intermarriage/endogamy & location context if you know of such a thing.
