A woman converted to Judaism to marry a man who was a practicing Jew and Jewish by birth. Their great-grandchild recently learned this. Is that great-grandchild considered a Jew according to halacha? The specifics of the conversion are not currently known.
What I have read says that the child of a Jewish woman is a Jew, even if this is not recognized by the mother or the child. This suggests that the grandmother was a Jew which suggests that the mother was a Jew which suggests the child is a Jew. Is that correct?
Edit: Thanks everyone for your comments. I will take your general advice and visit my local Synagogue and consult a/the Rabbi there for further advice and information.
