Yevamot 49: Who Is a Mamzer?

A new mishnah! And more on mamzerim, even an introduction to the status. Plus, a genealogy scroll that includes mention of a person as "mamzer." Also, the second half of the mishnah... The impact of a woman who dies on her sister's permissibility to marry a whole slew of people. Also, spotlight that lineage scroll. With insights, as it were, from the prophet Isaiah. What does his position, as presented in the Gemara, imply about prophecy? Plus, another extra meta comment about the mishnah.
