My question involves name change laws in the State of: Ohio. When my daughter was born, the mother gave her her last name which is the last name of the man that she was married to and he is deceased. For example her maiden name is "Smith" but her married name is "Jones". My daughter's last name is "Jones". The mother and I were not married and paternity was established. I would like to have my name on her birth certificate and her name changed to my last name. This woman and I have 2 daughters together and the oldest carries my last name. Would the mother have to agree?
