Since you are going through a divorce, you might want to consider getting an emergency temporary order to keep the brothers away and protect your daughter while this is being sorted out. Also, this was posted in the family law area. You may want to post in criminal regarding whether an additional law was broken and a civil defamation area regarding suing for monetary damages. However, from a family law point of view you maybe would want to focus on protecting the child at this point, in addition to suing civilly or having charges being brought against the ex. This sounds like a complicated situation where it would be helpful to have a family law attorney to guide you.

What you describe here is:
1) A very serious criminal investigation against your husband's juvenile brothers;
2) A very complicated and sensitive divorce case;
3) A Child Protective Services case that has the potential to lead to a Dependency case.
All three of these things, independently of one another, carry the threat of devastating consequences.
To bring a law suit for Defamation, you would have to prove:
1) False statements made about you;
2) False statements about you were published;
3) False statements, published, caused actual damage to you.
This is generalized, there are some exceptions.
Truth is a defense in a Defamation case.
The first thing you should do is consult with a family lawyer who can help you sort all of this out. Your obvious priority is to protect your children from harm. If a valid and worthwhile Defamation claim surfaces, ask your family lawyer for a referral to a lawyer who can handle such a claim.
