My birth name is not Gross. My brother is my half brother. We have the same mother and different fathers. My mom says my brother's father died when he was a baby. We do speak (my mother and I) but she has pretty much lied about everything including her identity. I do have a sister Amanda. We share the same mother (Elly Jean) and the same father. We want brother's birth certificate so we can find out name my mother was using before she changed it. That way, we can trace her family line.
