My question involves name change laws in the State of: Mississippi/Louisiana/Kansas

My daughter was born in Kansas. The father is not listed on the birth certificate, but she has his last name. I moved to Louisiana to get away from him and the abuse after a temporary order of protection was issued. I have a Louisiana driver's license, but recently moved to Mississippi about 2 weeks ago. (Confusing, I know.)

My question is this:
How do I change her name to my maiden name and which state does it have to happen in? I don't even know which state I am a legal resident of! Her father has not been involved in her life, he does not support her in any way, he is not listed on the birth certificate, and he is a drug addict/dealer with a felony conviction. How do I fix this?
