Acts 17, Rom. 5 seem to suggest that.

it seems to be the most logical conclusion in light of the scriptural
silence about the names of daughters or women unless they are significant
figures such as Eve, Miriam, or Sarah.
1.3.1 was
in-family marriage

It was only stated in the Pentateuch that intra-familial marriage was
prohibited. It seems that as the human families proliferate, it was
imperative to God to lay down rules for blood relations. Before the
worsening of the fallen human society, mutations in human genome may be of
a relative minor nature such that inbleeding in human families did not
significantly increase the expressions of these mutations. After Noah's
flood and the tower of Babel, human conditions have worsened to such a
degree that God prohibited intra-familial marriage to prevent expression
of recessive genes.

It was prohibited in Genesis in the case of Lot and his daughters.
However, the Scripture was silent before this. In fact, Sarah was
Abraham's half sister.
