I am using BanyonDNA to validate my relationship to my atDNA matches (at least those I have determined). I have atDNA matches for which I have determined up to six different relationships. I start using the relationship calculator in RM to determine how many ways I am related, but am not sure I am interpreting the list of relationships correctly. For example, my 2nd great grandparents maybe the MRCA, but the parent of the same 2nd great grandfather is also listed. I assume this is due to a relationship via a sibling of my 2nd great grand parent. But have not determined an easy way to search for this additional relationship path. This is complicated when the spouse of a cousin is also a cousin. Do any of you smart people have a way other than the brute force method of determining all the descendants out to my 5th great grand parents. I seem to share too much DNA with many of my atDNA matches, so I may have undiscovered relationships, but when I add all my known relationships it seems to only make a small difference in the expected amount of atDNA.

There are SQLITE methods that might get you what you want.

Yes you are right that it would be a sibling of your 2nd g-grandfather if his parents are listed.
Have you tried using the RELATIONSHIP CHART under Publish to determine a way to search for this additional relationship path?
As for a way of finding all the descendants ( assume you want descendants only --not spouses also) of your 5th g-grandparents, you could make a group of direct descendants (or do a saved search–then make a group ) and color code it-- then rinse and repeat for however many 5 g-grandparents you have–just making a new group and color coding it a different color–I may be wrong but I would think you would just have to have 1 group per set of 5th g-grandparents AS LONG AS THEY WERE BOTH ONLY MARRIED ONCE-- if 5 g- gramps had 3 wives–I would do a separate branch for each wife..
I may be wrong BUT once you have your groups, you could manipulate the groups to see if someone shows up in 2 different lines such as if your grandma was a descendant of your 5th g-grandparents Smith and also a descendant of your 5th g-grandparents Jones…
I’m sure if I am wrong, someone will tell us and / or give more guidance as I have NOT tried this…
edit–there are also a couple of DNA reports if you are using RM’s new DNA BUT I don’t know enough abt them to tell you how they MIGHT help..
