Can We Marry Ahlul Kitab?

Question:  I fell in love with a single mum who is a catholic woman. If she convert to muslim, may I know how is the child who have already been baptized as a catholic? Is it permissible for a muslim man to marry a catholic woman if she decide to keep her faith… – Anonymous, Singapore
