In some states, grandparents do have rights. This sounds like you need to find some legal help for sure. If you look in the phone book, they usually have some kind of "legal aid" where you pay a small fee and they can help you pick out an attorney that has experience in that particular field, then maybe you could see him/her and see if they would take the case pro bono. I do hope you get to keep the boy or boys, if the one doesn't want to live with his dad. As far as your daughter is concerned though, there's not a thing you can do about it. She's an adult, and even if she's heard things about this guy, it's not going to change anything, but she'll find out how "good" her life will be.
