First of all the private parently test that you took will not be allowed for use in the court. The court would make you take another one and although that may result in you being the father,that will not give you alot of rights. The promblem is the mother being married and having another name put on the childs birth certificate meands that there is another man that has claim to the child. The court could allow you to change the childs last name and you would have to go to court and ask the court in order to do that and if that can be done then you have the door open to file for custody and yes you being the father would override the grandparents rights. I would consult an attorney and get this done legally.
