I'm sorry to hear about your situation. Unfortunately, there is not really anything that you can do against her unless anything she says is untrue. Convictions are a matter of public record. The type of lawsuits that are usually available in a situation where someone is spreading information is either defamation/libel/slander or invasion of privacy and false light. But for someone to be defamed or to be portrayed in a false light, the things that are being said have to be untrue. And for invasion of privacy it has to be a private fact...and public records are not private facts. So unfortunately, while it is terrible that you are being put in this position, you don't really have a good action against her unless she makes a mistake and says something that is untrue.
I notice you haven't rated me yet. Was there any additional information you needed?
