Father A nor Father B was married to the mother.
That would just change the purple things on my previous picture, i.e father A being the grandfather.
- Person-in-question and Known-grandchild would be
half-first-cousins,
156-979(449)- Person-in-question and Known-great-grandchild would be
half-first-cousins-once-removed,
62-469(224)The green side of the previous picture still applies (since this example is only comparing with known descendants of father A). So if father B was the person in question's grandfather the relationships and numbers are unchanged.
- Person-in-question and Known-grandchild would be second-cousins, 41-592(229)
- Person-in-question and Known-great-grandchild would be second-cousins-once-removed, 14-353(122)
By comparing the actual DNA matches with the expected ranges for the two scenarios you can see whether they match one, the other, both, or neither, and draw inferences from the results of tht. E.g.
- If the match to the grandchild is >592 and to the great-grandchild >353 then father A is very likely (almost certainly?) the person in question's grandfather.
- If the match to the grandchild is <156 and to the great-grandchild <62 then father B is very likely (almost certainly?) the person in question's grandfather.
