Tresspassing Charges

We told our sister and brother in law they were not permitted on our premises any longer as they have been harrassing our family, accusing uf of theft and causing emotional harm to my mom who lives with us. My brother in law tried to force his way into our home last week and my husband shoved him back out the door. He tried to force his way in again and my husband shoved him again. He bounced off the wall of the porch and fell backwards down the steps. He stayed for 10 more minutes trying to get back into house when a neighbor called the police. He now is filing simple assault and harrassment charges against my husband. My mother told the police officer he tried to force his way in and we told the officer that as well but he did not add that information to the police report. Our neighbor also witnessed the brother in law trying to come back up the steps several times. Can we file defiant tresspassing charges and does anyone know if we can get one restraining order for all of us in the house for does my mom have to get her own. My sister also went to my mother's boss and told her all about our family issues. Isn't that considered harrassment as well with grounds for restraining order?
