do you have a putative father registry in your state? i may be wrong, but i believe that what it was created for. if a man thinks it's possible that he fathered a child, it is his responsibility to sign up on this registry, stating that he wants to be notified of any legal goings-on involving his child. also, is your attorney running an ad in the paper notifying any potential fathers of this child to step foward? i would think that if they've tried to find him, in addtion to what i mentioned above, would be plenty of grounds to terminate his rights and that he wouldn't have much basis at all to try and regain parental rights in the future.
just my 2 cents...i may be wrong. it wouldn't be the first time
