If a woman converted before she conceived any children are they considered Jewish? Even with a non-Jewish father? I understand that non-Jewish mothers with Jewish husbands do not have Jewish children because the Jewish line is maternal, but I am referring to a woman who converted to Judaism prior to getting pregnant, which would make her a Jew. Would that make her children Jewish also because their mom is now considered Jewish, or is it a different situation than natural Jewish mothers?
Yes. Children of a Jewish mother are Jewish, regardless. If mom converted she's Jewish. (A child who was in the mother's womb when mom converted is also Jewish, by the way.)
