RE; I was thinking more of Mr. and Mrs. Noah.
There were 8 people in the Ark, 4 couples.
half of which sprang from the original two...
thus the others would have the link.
But weren’t Noah and his wife parents of the males in the other three couples? That would make he and his wife the oldest surviving progenitors, post-apocalypse grandparents of the human race.
Genesis 7:7 And Noah went in, and his sons, and his wife, and his sons' wives with him, into the ark, because of the waters of the flood.
Noah's daughters-in-law were not descendants of Noah and his wife.
The only two people from whom all humans are descended can only be Adam and Eve.
Noah, his wife, his 3 son’s and their wives all trace their ancestry to Adam and EVE, through the mitochondrial DNA that all humans get from their mothers.

Noah and his sons and wives came from Adam and Eve.
But they wer3 all related to... Noah and his wife.
