I just looked at the Tur and he does not say this at all. On the
contrary, he says that unless all ancestors are gerim, one may *not*
marry a mamzer/es, and a girl *may* marry a Cohen.

However, unlike the Rambam and Shulchan Aruch, the Tur does rule that
this heter to marry mamzerim expires after literally 10 generations,
because of mar'is ho`ayin. This is the first mention I've ever seen in
any halachic source of 10 doros as a shiur for anything. The BY says
it's a machlokes in a braysa: the Tana Kama says 10 doros, but Yesh Omrim
that it's however long it takes for it to be forgotten that the family
are gerim. The Rosh paskens like the Tana Kama, the Rambam like the
Yesh Omrim; the Tur follows the Rosh, and the SA the Rambam.

Note however that everyone agrees that be'etzem the family remains gerim
forever, so long as no Yisrael married into the family, and if not for
mari'is ho`ayin they would be allowed to marry mamzerim forever.

The Ran, as you note, says it goes after the father, so a ger's son from a
Yisre'elis may marry a mamzer, but a Yisrael's son from a giyores may not.
And presumably this goes on forever, or as long as it's remembered that
the family are gerim.

No, he is not.   I think you are confusing Reikhav (with a khaf, and
a tzeireh under the reish) with Rachav (with a ches, and a kamatz
under the reish).   Reikhav was (1) a man; (2) descended from Yisro;
and (3) several centuries after Rachav.
