I need some assistance about naming my novel?

Well the way I am thinking about titling my novel is ([main character] and [the subtitle]). I thought this would be excellent but then a few weeks later I realized that the famous Harry Potter series was titled in that fashion. I am a huge Potter fan and did NOT steal the idea for this fashion. I guess it was just a coincidence. Anyways, I am looking into to getting my novel published after it is fully finished and I do not want it to seem like I am stealing that fashion or copyrighting anything. So my question is should I keep my title in this fashion or change it? And are and other novels titled like this besides Harry Potter? Thanks!
