A Mamzer or Doubtful Mamzer, Who to Marry
The Book Mishpitei Yisroel describes the teachings of the greatest
rabbis of Israel and America in divorce. Forcing a husband to give his wife a
GET is generally forbidden, and even causes the woman who remarries without a
kosher GET, to produce a child from the second husband who is a mamzer.
Because today few even rabbis are experts in laws of marriage and
divorce, many of them, even senior ones, encourage women to force the husband
to divorce. These women remarry and have children from the second husband who
are born mamzerim. But that is not the whole tragedy. A mamzer may marry a mamzeres.
But a doubtful mamzer may not marry a mamzeres, nor may he marry a regular
Jewish woman. [1]
See also Shulchan Aruch Even Hoezer 4:20 and the poskim there how a
mamzer can marry to have kosher children. There is a question if today such a
thing is permitted, which is not our topic here.

Shulchan Aruch Even Hoezer 4:24. See also Baare Haytiv there 4:24 if a shifcho
or eved is permitted to marry a mamzer or a doubtful mamzer and the fate of the
children of such a marriage.
