MY daughter is nearly 8 months old. I gave her the last name of her father (although we are not married) and he left us several months ago. When he left I was adament about being update when his contact information has changed and he has neglected to follow through on doing this.

I would like to give her my last name because he now has nothing to do with her, and I suspect that he never will. I understand that the laws are different from state to state and that there is a difference in the protocol if the child is over 1 year of age. She was born in Maine and we now live in Illinois so I don't even know where to begin.
