Daughter interfering

Can someone please tell me if I can get a restraining order against my 19 yr old daughter for interfering with my 16 yr old son, and 14 yr old stepson. It is not physical. She is trying to make decisions behind my husband and myself’s back to help their missing parents be able to see and talk to them. These 2 left and moved to wv and will not give us a address or phone number to get in contact with because they are afraid they will have to pay child support, so they are using her to get to our kids. If more information is needed please ask, I am at my wits end with my daughter.

There is no basis for a restraining order on these facts.
