Incest after the flood

[CuriousInIL]

There have been a number of questions about incest and marriage after Adam & Eve. Wouldn’t there have been a similar issue of inter marrying after the flood? The farthest relationships would have been the cousins that were Noah’s grandchildren, right?
Does this also mean that, just like all are descended from Adam and Eve, all are descended from Noah and Mrs. Noah (according to Jewish tradition her name is Naamah)?

There were three other couples on the boat besides Noah and Mrs. Noah:

*Genesis 7:13 On the very same day Noah and his sons, Shem and Ham and Japheth, and Noah’s wife and the three wives of his sons with them entered the ark, *

The wives of Noah’s sons would not have been his direct descendants, so in that sense (grandchildren had blood other than Noah and his wife’s) it wouldn’t be correct to say “all are descended from Noah and Mrs. Noah”.

Good point. I should have said descended from the Noah family.
