I think you need to do what works for the story you’re creating! If romance doesn’t fit then don’t feel the need to add it in. In fact there are quite a few readers who will probably be glad there’s not romance or an abundance of it in the story. 
As for titles (I’m not good at this part) maybe something like “Roots” since it’s about her discovering where she came from.
Good luck on your story by the way!
