I am not sure where to start with my question/problem. I would like to hyphenate my daughter's last name with my new married last name. She is 7 and asked if she could have the same last name as me and my husband, her step-father. She was born in MD, we are moving to VA (we are military), I am a resident of AK and her biological father lives in OR. I do not know which state to start the proceedings! Her biological father is okay with the name hyphenation. Help!
