Can i reuse it ?

So, my brother & his girlfriend are having a baby. If it's a boy his name's gonna be Anthony Lee. But if it's a girl, they like the names Emmaleah or Hazel, but dont really know about what to do about the middle name for her, but she said tht once she gives birth, she'll probably think of something she likes. But anyway its gonna be Anthony after my brother & mines dad, but i was planning on giving my future son Anthony as a middle name. If it does turn out to be a boy, im afraid i wont be able to use it. Because i dont want people to say * oh, well she just did tht to copy off of them*, you know what i mean ? But tell me what you think about it in the comments.
