Should I keep Isadora for my baby's name?

So, my wife and I were choosing names. If it's a boy, it will be August. We were struggling to find girl names. My wife suggested that we choose a Brazilian name for a girl (I'm Brazilian). My wife fell in love with the name Isadora and I like it too. However, I remembered, after my in-laws were in love with the name, that a childhood friend's daughter is called Isadora. We are not close anymore, we barely talk but we are still friends on FB. Now I don't know if I should keep the name. I don't want her to think I stole her baby's name. In my culture, we try not to duplicate names among families and friends. On the other hand, we love the name. It might sound stupid to ask for opinion here, but I'd like some feedback that might shed a light in my decision. Thanks!
