R’ Eliezer ben Yaakov says: [If] a non-Kohen married a proselyte, his daughter is qualified to marry a Kohen; [if] a proselyte married the daughter of a regular Jew, his daughter is qualified to marry a Kohen. However, [if] a proselyte married a proselyte, his daughter is disqualified from marrying a Kohen. [This applies to] both a proselyte and freedmen, even until ten generations, unless his mother is of Jewish descent. R’ Yose says: Even [if] a proselyte married a proselyte, his daughter is qualified to marry a Kohen.

One who says: “ This son of mine is a mamzer,” is not believed. Even if they both say, concerning the fetus in her womb: “ He is a mamzer,” they are not believed. R’ Yehudah says: They are believed.
