Kiddushin 67 - October 19, 4 Cheshvan

Study Guide Kiddushin 67 We continue to learn for the safety of our soldiers, residents of the South and the North, and the whole country, the safe return of the captives, in memory of those who have fallen and for a refua shleima to all those injured.  What are the rules in determining the lineage of a child?  The Mishna lists four different types of marriages. It depends on the situation - whether the betrothal was permitted or forbidden, as well as other criteria. But aren't there other cases that should be listed, such as a convert and a mamzeret, as Rabbi Yosi rules the child follows the father? The Mishna is explained in two different ways - like Rabbi Yehuda and Rabbi Yosi. From where do we derive that a betrothal with one is who a forbidden relative will not be effective at all?
